* To update file handling for the new DR host linking mechanism, file_locations -> file_location_anvil_uuid was changed to file_location_host_uuid.
This required a fair number of changes elsewhere to handle this, with a particular noted change to Database->get_anvils() to look at host_uuid's for the subnodes in an Anvil! and, if either is marked as needing a file, make sure the peer is as well. Similarly, any linked DRs are set to have the file as well.
* Created a new Network->find_access that simply takes a target host name or UUID, and it returns a list of networks and IPs that the target can be accessed by.
* Updated Network->load_ips() to find the network interface being used for traffic so that things like the interface speed can be recorded, even when an IP is on a bridge or bond.
Unrelated, but in this commit, is a restoration of calling scan agents with a timeout now that the virsh hang issue has been resolved.

* In Cluster->parse_cib(), added parsers for node attributes and resource rules. Also stored the existence of and details of each under the server resources for easier referencing.
* Updated scan-server to check for / add DRBD fence rules as needed.
Scancore APC agent bugs;
* For clarity, converted all '#!no_value!#' and '#!no_connection!#' to use '!!' instead in APC scan agents.
* Fixed a bug to set/clear alerts related to phases disappearing to deal with concurrent logins from different hosts triggering false phase loss alerts.
* Fixed missing variables not being passed to alerts/log entries.

* Updated scan-network to check for the 'default' virbr0 interface by checking if the config file exists instead of calling virsh.
* Updated scan-server to have better logging.
* Created the new (and incomplete) anvil-test-alerts tool
* Updated scancore to support --purge to pass to all agents and then exit.

* Updated Database->resync_databases() to never run on non-striker machines. On Strikers, before a resync, _age_out_data() is called to clear old data in long-off databases.
* Created System->check_memory() that is loosely based on anvil-check-memory, but checks to see if it's being controlled by a systemctl started daemon and, if so, reads the RAM in use from it's status output.

* Created ScanCore->agent_shutdown() that writes out the time the scan agent last ran, and how many databases were available when it last ran.
* Updated ScanCore->agent_startup() to read the the last run data created above.
* Updated Database->connect() to set 'sys::database::last_db_count' to the scan agent's recorded last DB count.
* Updated all agents to call ScanCore->agent_shutdown() at the end of their run.

* Bumped scancore's scan delay from 30 seconds to 60.
* Shorted the age-out time to 24 hours and again boosted the archive thresholds. As we get a feel for the amount of data collected on multi-Anvil! systems over time, we may continue to tune this.l
* Moved Database->archive_database() to be called daily by anvil-daemon, instead of during '->connect' calls.
* Added locking to Database->_age_out_data to avoid resyncs mid-purge. Also moved the power, temperature and ip_address columns into the same 'to_clean' hash as it was duplicate logic.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Created Database->_age_out_data() to delete records from the database that are old enough to no longer be useful. This is designed to significantly reduce the size of the database, allowing a better focus on performance.
* Changed Database->connect() to default to NOT check for resync, reworking the old 'no_resync' to 'check_for_resync', so that resync checks happen on demard, instead of by default.
* Updated get_tables_from_schema() to now allow 'schema_file' to be set to 'all', which then loads the schema files of all scan agents as well as the core anvil schema file. Fixed a bug where commented out tables were being counted.
* Re-enabled triggering resyncs on 'last_updated' differences.
* Fixed a bug in scan-ipmitool where the history_id column in history.scan_ipmitool_value was incorrect.
* Created a new tool called striker-show-db-counts that shows the number of records in all public and history schema tables for all databases.
* Updated anvil-update-states to detect when a libvirtd NAT'ed bridge exists and to delete it when found.
Signed-off-by: Digimer <digimer@alteeve.ca>
* DRBD is now configured to a ping-timeout of 3 seconds.
* Created Log->switches() that returnes the command line switches used by Anvil! tool command line calls based on the active log levels / secure logging. Appended this to all invocations of our tools.
* Updated Database->resync_databases() to now only skip 'jobs' and 'variables' tables with less than 10 record differences. All other differences will trigger a resync.
* Created System->_check_anvil_conf() that, as you might guess, checks in anvil.conf exists and created it (using defaults), if not. It also checks to see if the 'admin' group and user exists and creates them, if not.
* Updated anvil-daemon to check anvil.conf on start up and in each loop. Created the function check_journald() that checks (and sets, if needed) that journald logging is persistent.
* Made striker-manage-peers to check_if_configured on the Database->connect() when updating anvil.conf and the target UUID is the local machine. Also created a loop to make the reconnection a lot more robust.

* Fixed a bug where 'fence_data::updated' was causing the fences web page to break.
* Fixed a bug in Database->insert_or_update_network_interfaces() where certain interfaces were being repeatedly added to the database.
* Fixed a bug in Database->_find_behind_databases() was marking DBs as behind even though they had less than 10 columns off.
* Fixed a bug in Get->host_name() where, if the host name was changed on disk but the environment variable was still the old name, it would cause the hostname to waffle back and forth and cause constant updated to /etc/hosts.

* Updated the scan agent timeout to 60 seconds. Also made the scan agent exit code log entries more helpful.
* Updated System->collect_ipmi_data() to now better handle duplicate sensor names. Now, instead of simply appending an integer, we find the hex address and use that in the sensor name when duplicates exist. This solves the problem of the sensor names not being consistently shown in order.
* Fixed message bugs (bad variable insertions) in scan-apc-pdu and scan-apc-ups.
* Fixed schema procedure bugs in the 'temperature' and 'ip_address' tables where the columns were in bad order, causing constanty updates.
Incomplete work;
* Create the shell of 'anvil-manage-storage', but virtually no logic exists in it yet.
* Started work on anvil-safe-start to deal with an issue where DRBD resources don't start when a server is running on a peer.

Signed-off-by: Digimer <digimer@alteeve.ca>
* Added a new parameter to Database->connect() called 'no_resync' that, if set, prevents a resync check being performed. Updated ->resync_databases() to find a uuid_column where the table name ends in 'ies' and the UUID column is 'y_uuid'. Updated ->resync_databases() to not fire on updated table age anymore, and to trigger only if the number of rows differ in a given table by more than 10.
* Updated Log->entry() to prefix a tool's name, when the new 'log::scan_agent' value is set. Also set this value in ScanCore->agent_startup(), to help differentiate log entries.
* Fixed a bug in scancore's main loop where it logged the sleep message at the start of the run.

Signed-off-by: Digimer <digimer@alteeve.ca>
* Created DRBD->check_if_syncsource() and ->check_if_synctarget() that return '1' if the target host is currently SyncSource or SyncTarget for any resource, respectively.
* Updated DRBD->update_global_common() to return the unified-format diff if any changes were made to global-common.conf.
* Created ScanCore->check_health() that returns the health score for a host. Created ->count_servers() that returns the number of servers on a host, how much RAM is used by those servers and, if available, the estimated migration time of the servers. Updated ->check_temperature() to set/clear/return the time that a host has been in a warning or critical temperature state.
* Finished ScanCore->post_scan_analysis_node()!!! It certainly has bugs, and much testing is needed, but the logic is all in place! Oh what a slog that was... It should be far more intelligent than M2 though, once flushed out and tested.
* Created Server->active_migrations() that returns '1' if any servers are in a migration on an Anvil! system. Updated ->migrate_virsh() to record how long a migration took in the "server::migration_duration" variable, which is averaged by ScanCore->count_servers() to estimate migration times.
* Updated scan-drbd to check/update the global-common.conf file's config at the end of a scan.
* Updated ScanCore itself to not scan when in maintenance mode. Also updated it to call 'anvil-safe-start' when ScanCore starts, so long as it is within ten minutes of the host booting.

* The get_mmeory endpoint was completed.
* The get_replicated_storage endpoint was completed, though it requires testing and likely has issues.
To prepare for the get_status endpoint work, I needed to update ScanCore and modules to track the host_status. This commit contains the work needed for this.
* Updated ScanCore->post_scan_analysis_striker() to use configured fence devices (except PDUs) to check if a target host is off or on, in there is no host_ipmi interface. In all cases, if a machine can be confirmed on or off, the host_status is now updated.
* To support the above fence based power checks, updated scan-cluster to store the on-disk CIB in the new scan_cluster -> scan_cluster_cib colume.
* Updated ScanCore->parse_cib() to map stonith primitive IDs to fence agents. Updated ->parse_crm_mon() to not call if the executable doesn't exist to avoid unhelpful error messages in the logs when called from a Striker.
* Update DRBD->gather_data() to get the size data from /sys/block/drbd<minor>/size' x '/sys/block/drbd<minor>/queue/logical_block_size so it works when a device is Secondary (and can't be promoted).
* Updated Database->get_hosts_info() to record the short host name as well as the stored host name. Created ->update_host_status() as a wrapper to ->insert_or_update_hosts() that only updates the host status.
* Updated anvil-join-anvil to disabled ksm and ksmtuned daemons.
* Updated scancore and anvil-daemon to set the host_status to 'online' on startup.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Fixed a bug in ScanCore->agent_startup() where a (thankfully broken) check to append tables to the 'sys::database::check_tables' would cause an infinite loop as both were pointers to the same anonymous array.
* Fixed a bug in scan-ipmitool where the scan_ipmitool_variables table didn't use a host_uuid reference, causing resyncs of that table to sync for all hosts and cause DB errors when the scan_ipmitool record from another host wasn't sync'ed yet.

* Updated Get->os_type() to use 'cat' instead of Storage->read_file() because 'rsync' may not be available when it is called during striker-initialize-host calls.
* Updated Database methods to skip 'oui' and 'state' during resync.
* Updatedb striker-initialize-host to detect when it's initializing a CentOS Stream Node / DR Host and enable the HA repo.
* Created the tools/striker-auto-initialize-all tool, which is very much incomplete, that will allow for the rapid creation of a full Anvil! from freshly installed machines autonomously.

* Started work on Get->available_resources() that will take an 'anvil_uuid' and figure out what resources are still available for use by new servers or that can be added to existing servers.
* Fixed a bug in ScanCore->agent_startup() where tables weren't being generated properly from the agent's SQL file.
* Made Storage->change_mode() return silently if it's called without a mode being passed. This happens frequently and is harmless so it's not worth filling the logs with errors.
* Renamed the 'start_time' key to 'at_start' when recording files' MD5 sums in Storage->record_md5sums and ->check_md5sums.
* When we moved the directory scan logic out of the 'scancore' daemon and into 'Storage->scan_directory', the logic to record scan agent names in 'scancore::agent::<file>' was removed. This broke a few things and, so, it was restored when it was found that a file starts with 'scan-' and the directory matches the scancore agent directory.
* Moved the 'scancore' daemon's 'load_agent_strings' to 'Words'
* Updated Words->parse_banged_string() to look for variables in the format 'value=X:units=Y' and translate it properly.
* Fixed a bug in scan-ipmitool where discovered sensor INSERT SQL queries were queued, but not committed.
* Fixed a bug in scan-storcli where a while loop was broken, preventing execution.
* Fixed a bug in the 'scancore' daemon where it wouldn't exit if sums changed. Fixed a bug where alerts weren't being sent between loops. Fixed a bug where command-line log level wasn't surviving inside the main loop.

* Created Database->get_power() that loads data from the special 'power' table.
* Fixed a bug in calls to Network->ping() where some weren't formatted properly for receiving two string variables.
* Updated Database->get_anvils() to record the machine types when recording host information.
* Updated Database->get_hosts_info() to also load the 'host_ipmi' column.
* Updated Database->get_upses() to store the link to the 'power' -> 'power_uuid', when available.
* Created ScanCore->call_scan_agents() that does the work of actually calling scan agents, moving the logic out from the scancore daemon.
* Created ScanCore->check_power() that takes a host and the anvil it is in and returns if it's on batteries or not. If it is, the time on batteries and estimate hold-up time is returned. If not, the highest charge percentage is returned.
* Created ScanCore->post_scan_analysis() that is a wrapper for calling the new ->post_scan_analysis_dr(), ->post_scan_analysis_node() and ->post_scan_analysis_striker(). Of which, _dr and _node are still empty, but _striker is complete.
** ->post_scan_analysis_striker() is complete. It now boots a node after a power loss if the UPSes powering it are OK (at least one has mains power, and the main-powered UPS(es) have reached the minimum charge percentage). If it's thermal, IPMI is called and so long as at least one thermal sensor is found and it/they are all OK, it is booted. For now, M2's thermal reboot delay logic hasn't been replicated, as it added a lot of complexity and didn't prove practically useful.
* Created System->collect_ipmi_data() and moved 'scan_ipmitool's ipmitool call and parse into that method. This was done to allow ScanCore->post_scan_analysis_striker() to also call IPMI on a remote machine during thermal down events without reimplementing the logic.
* Updated scan-ipmitool to only record temperature data for data collected locally. Also renamed 'machine' variables and hash keys to 'host_name' to clarify what is being stored.
* Updated scancore to clear the 'system::stop_reason' variable.
* Added missing packages to striker-manage-install-target.

* Updated the servers table to remove the 'not null' constraints on the server_start_after_server_uuid, server_pre_migration_file_uuid and server_post_migration_file_uuid columns.
* Updated ScanCore->agent_startup() to connect to the database(s) when there isn't a table list.
* Updated Server->migrate_virsh() to test for DB access before making DB calls (to allow ocf:alteeve:server to function even if all ScanCore DBs are offline).
* Updated ocf:alteeve:server to connect to the databases (though work without it), and changed '$FILE_NAME' to be 'ocf:alteeve:server' (to make logging more legible)
* Created the skeleton for 'scan-storage'.

* Updated scancore, anvil-daemon, and scan agents to not run unless they're run with root privs.
* Got scan-server to update the servers / server_definition tables and the on-disk file when needed.

* Updated Alert->register to take a hash reference for message variables to simplify when a caller plans to log and register an alert at the same time.
* Updated Convert->bytes_to_human_readable() to name the 'size' variable used internally for 'bytes' to actually be 'bytes' for better consistency.
* Created multiple new Database methods;
** ->check_condition_age() is meant to be used by scan agents to see how long a given condition has been in play (ie: how long ago power was lost to a UPS or a sensor became unreadable).
** ->insert_or_update_health() handles recording data to the new 'health' table, used for determining ideal hosts for servers between nodes.
** ->insert_or_update_power() handles recording data to the new 'power' table, used for determining how power events are handled.
** ->insert_or_update_temperature() handles recording temperature data to the new 'temperature' table, used to determine how thermal events are handled.
* Got a lot more done on the scan-hardware scan agent. Only part left now is post-scan health processing.
