* 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.
Started more work on anvil-manage-server, but on hold again while the DRBD fencing work is completed.

* 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.

* Updated scan-cluster to get the CIB from pcs instead of reading the CIB from disk.
* Updated anvil-daemon to always call striker-prep-database at log level 2 while trying to find the cause of rare postgres config failures. Also updated striker-prep-database to use the new method of initializing the DB.

* WIP - Continuing work on the new anvil-manage-server tool.
* Updated Database->get_anvils() to load information on the files available on each Anvil! system.
* Updated Database->insert_or_update_network_interfaces() to no longer take the 'timestamp' parameter.
* Removed all logging from Database->refresh_timestamp() to speed it up, given how often it will be called now.

* 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.

* Created Cluster->check_stonith_config() that checks and, if needed, reconfigures a cluster's fencing (stonith) config.
* Updated scan-cluster to call Cluster->check_stonith_config() at the end of each call.

* 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.

* Reworked scan-ipimitool so that on nodes and dr hosts, it only scans itself. On strikers, it scans all hosts found in active Anvil! systems with a host_ipmi entry. `
* For all agents, reduced log verbosity to not push too much noise into anvil.log while scancore is running in the background.

* Updated Alert->register() to take message variables using the 'variables' parameter.
* Added a 'cache' parameter to Database->insert_or_update_health() and ->insert_or_update_temperature(). When set, the SQL UPDATE/INSERT calls and pushed into the array reference set in 'cache'. This is to allow performance improvements when processing a large amount of sensor/device data.
* Updated Log->variables() to take a 'prefix' parameter that, when set, will prefix the string to each variable line.
* Updated scan-ipmitool to use Database->insert_or_update_health() and ->insert_or_update_temperature().

* Fixed a bug if Get->free_memory() where host_type was still being called from the old System->host_type method.
* Added global support for '--log-secure' and '--log-db' switches to enable logging of secure data and DB transactions, respectively.
* Created Database->get_tables_from_schema() that parses a SQL schema file and returns an array reference of tables found, in the order they were found.
* Updated ScanCore->agent_startup() to no longer require manually defining database tables, using Database->get_tables_from_schema() when not manually set.. Updated all existing agents to use this.

* Created (but not finished) scan-apc-pdu
* Added support to tracking maintenance-mode for nodes in Cluster->parse_cib
* Created Remote->read_snmp_oid().

* Updated Server->get_status() to write-out server XML files on-demand.
* Finished scan-cluster.

* Updated Server->migrate_virsh() to set 'servers' -> 'server_state' to 'migrating' and clear it again once the migation completes. Also added support for cold (frozen) versus live migrations.
* Updated Cluster->parse_cib() to check if a server with the server_state set to 'migrating' isn't actually migrating anymore and, if not, to clear that state. This is needed as scan-server will blindly ignore/skip any migrating server, and if a migration call is interrupted, the state could get stuck.
* Updated the 'servers' database table (and associated Database methods) to add columns for;
** server_ram_in_use - tracking RAM used by a running server
** server_configured_ram - RAM allocated to a running server (used with the above to alert a user and track _currently_ available RAM)
** server_updated_by_user - To be set by Striker tools to indicate when the user made a change that needs to push out to nodes / running server.
** server_boot_time - Tracks the unixtime when the server booted (to track uptime even if the server migrates across nodes).
* Created Get->anvil_name_from_uuid() to easily convert an Anvil! UUID into a name. Also created ->host_uuid_from_name() to translate a host name into a host UUID.
* Created Server->get_runtime() that translates a server name into a process ID and then uses that to determine how long (in seconds) it has been running. This is used when a server transitions from 'shut off' to 'running' to determine exactly when the server booted (current time - runtime).
* Renamed all 'Server->parse_definition' calls that used 'from_memory' to 'from_virsh' to clarify the data source.
* Made scan-hardware smarter about RAM change alerts.
* Updated scancore to load agent strings on startup so that processing pending alerts works properly.

* Renamed the 'defitintions' table to 'server_definitions' to clarify the purpose, and made all the 'server' columns have then 'not null' constraint.
* Created Database->insert_or_update_servers(), ->get_servers(), ->insert_or_update_server_definitions() and ->get_server_definitions().
* 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.

* Added support in anvil.conf to disable scan agents with 'scancore::<agent_name>::disable', and added handling this to agents. Also allowed for '--force' to override this setting.

* Did more work on parsing server data out of the CIB. There is still an issue with determining which node currently hosts a resource, however.
* Renamed Server->boot to ->boot_virsh, ->shutdown to ->shutdown_virsh and ->migrate to ->migrate_virsh to clarify that these methods work on the raw virsh calls, outside of pacemaker (indeed, they are what the pacemaker RA uses to do what pacemaker asks).
* Got more work done on the scan-cluster SA.
* Created the empty files for the pending scan-server SA.
Signed-off-by: Digimer <digimer@alteeve.ca>
