* Reworked DRBD->get_next_resource() to pull from the database, and to no longer do that increments-of-three nonsense. Avoidable complexity. Also added a call to Cluster->get_anvil_uuid() if the 'anvil_uuid' parameter wasn't passed.
* Updated Database->get_host_from_uuid() and ->get_hosts() to now take 'include_deleted' parameter and default to not returning deleted hosts. This fixed issues where anvil-{delete,provision}-server calls could assign jobs to now-deleted hosts with reused host names.
* Updated anvil-delete-server to print log entries to STDOUT. Also updated it to not wait of shutdown of a server in pacemaker to complete, and instead to destroy it after calling pacemaker's resource stop. Updated to also check to see if the server being deleted is already out of pacemaker and, if so, skip that step and directly try to destroy the server, if it's running.
* Updated anvil-provision-server to force 'peer_mode' runs to pull their TCP Port and DRBD minor numbers from the job. This fixes a bug where the same resource on two machines could use different TCP ports.

* Added checks to anvil-provision-server to see if an existing server name is flagged as DELETED, instead of outright rejecting a given server name.

Note: These changes below shouldn't have been in this branch... *sigh*
* Fixed an issue with tools/anvil-provision-server where a VM would be created but didn't boot. When this happens, an explicit boot is sent via virsh. Also bumped up the time it waits for a new server to start up.
* Added an explicit call to scan-drbd after a new resource is created to ensure that if any calls come after looking for the next free DRBD minor or port, they don't use the ones just used.

* Fixed a bug in anvil-provision-server where forcing initialization of a new DRBD resource when running on node 2 would fail because the node ID in the drbdsetup command was hard-coded to be run from node 1.

* Updated Cluster->add_server() to now set failure timeouts to actual numbers instead of INFINITY after discovering that INFINITY doesn't work in those cases.
* Updated Databsae->get_hosts to now check if other entries have the same host name, and if so, to set their host_key to 'DELETED'. This should make it easier to handle when a hardware machine is replaced by new hardware but uses the same host_name.
* Updated Email->check_queue() to start and enable postfix.service if it's found to not be running.
* Updated Get->available_resources() to return '!!no_data!!' when a given host hasn't got any data in scan_lvm_vgs. Now use this in anvil-provision-server to exit if a node or dr host hasn't run scancore yet.
* Fixed a bug in scan-lvm where the pvs_uuid wasn't being loaded properly, preventing lost PVs, VGs and LVs from being flagged as deleted.
* Started work on anvil-migate-server, though it's far from complete.

* Fixed a bug in Cluster->shutdown_server() where the wrong variable was being evaluated when checking the server state.
* Created DRBD->delete_resource() that deletes a resource's backing device and configuration. Note that this wipes the DRBD MD and and FS signatures before removing the LV. Updated DRBD->gather_data() to record the backing devices for volumes.

* Fixed a bug in Cluster->parse_cib() when a server that is off wasn't setting 'status'.
* Renamed 'server::location::<server>::host' to '...::host_name' in several places.
* Got more work done on anvil-delete-server, up to the point where it calls the new Cluster->delete_server() method.
* Updated fence_pacemaker to call 'drbdadm adjust all' to dampen an issue where in-memory fence configs seem to change, preventing reconnection of the peer after it reboots from the fence. More testing needed on this issue.

* Removed the exit-if-no-DB check in ocf:alteeve:server so that (hopefully, needs testing), running servers won't be impacted if the nodes lost contact with both/all strikers.
* Updated scan-server to make an explicit check for missing XML definition files on startup and write them if needed.
* Very beginning work on anvil-delete-server has been started.
* Updated anvil-provision-server to wait when it's running in peer mode until the new XML definition is in the DB and then write it out to disk before exiting. Also updated it to add the new server to pacemaker before exiting.

* Finished DRBD->get_next_resource() that returns the next available minor and the next free TCP port (with two free ports available after it).
* Created Storage->get_storage_group_details() that pulls together the LVM, storage group members and storage groups into one block of data.
* Made more progress on tools/anvil-provision-server. It now gets up to the point of creating LVs, creating DRBD resource files, loading them, creating metadata and up'ing the resource. It doesn't yet (successfully) force a new resource to primary.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Fixed a bug in scan-drbd that was still looking for the scan_drbd_resource_uuid from the resource config file. Also added a check to see if 'scan-drbd::resource_status' directory exists before trying to read the files in it.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Created the new method Cluster->get_primary_host_uuid() that returns the 'host_uuid' of the primary node in the given cluster. This is useful for external programs to figure out which node is primary. Example is provisioning a new server being assigned to the active node. Also created ->is_primary() that is a similar test to see if the active node is the primary node or not.
* Updated Cluster->parse_cib() and ->parse_crm_mon() to work on remote hosts.
* Updated Database->get_hosts() to store the short host names.
* Created Get->host_from_ip_address() that translates an IP address to a host_uuid and host_name, if it's an IP assigned currently to a known host.
* Created Network->find_target_ip() that simplifies finding which IP address to use when the caller wants to connect to a target host.
* Reworked the anvil-join-anvil to parse fence_arguments in a way that handles passwords with spaces in them.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Cleaned up upload.pl now that it isn't responsible for loading the file details into the database. It only sets a job for the local Striker to process the file and move it into /mnt/shared/files, copy it to peer dashboards, then load jobs for Anvil! members to sync the new file.
* Created Database->get_files() and ->get_file_locations() to load the respective data.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.

* 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 in Database->insert_or_update_power() where the check to see if 'power_ups_uuid' was passed in was reversed. Also fixed a bug where the convertion of the value to TRUE/FALSE for the old value wasn't being set correctly.
* Updated Server->get_definition() to only translate the host name to a uuid if the host uuid wasn't passed in. Added a sanity check on the UUID as well.
* Cleaned up how existing UPSes are displayed in Striker when managing UPSes. Also renamed the form's scan agents to match the real agent names.

Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.

* 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.

* Updated Alert->check_alert_sent() and the 'alert_sent' table to remove 'alert_name' as it really isn't helpful given record_locator.
* Created 'Database->purge_data' that takes an array of tables and, in reverse, purges them from the database(s). This also disables archiving and resync functions now.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.

* Dropped support for supporting imperial measurements in generated emails.
* Created Database->get_alerts() to read in alert data and ->get_recipients() to get the list of alert recipients.
* SQL Schema changes;
** Added 'alert_processed' to 'alerts' to track what alerts have been processed.
** Changed 'recipient_new_level' to 'recipient_level' now that we're only using 'notifications' as a per-host override for user/hosts alert levels.
** Removed 'recipient_units' as we're no longer supporting non-metric values.
* Updated Alert->register() to take strings for the alert level (which gets translated to integers).
* Created Email->get_current_server() to returned the mail_server_uuid of the active mail server (if any). Created ->send_alerts() to process unprocessed alerts and send emails to recipients.
* Updated Words->parse_banged_string() to take the 'language' parameter.

* Added the anvil.conf option 'sys::privacy::strong' that controls if the Anvil! ever "calls home". Initially, this controls DRBD's usage flag.
* Updated DRBD->get_devices() to track resources by their 'by-res' names as well and by the normal '/dev/drbdX' devices.
* To mitigate https://bugzilla.redhat.com/show_bug.cgi?id=1868467, updated Get->bridges() to parse the normal (non-JSON) data if we get invalid JSON output.
* Updated anvil-join-anvil to not disable, and in fact enable, libvirtd on boot. With DRBD 9, the original fear of a user accidentally booting a VM that's running on the peer no longer is an issue. By enabling it and leaving it on, Striker dashboard users won't lose their virtual machine manager link unless the node powers off. Also enabled actually updating the job progress, completing this tool!

* Updated Striker->get_fence_data() to parse the switches to make it easier to map a fence agent's command line switches to STDIN arguments.
* Created System->parse_arguments() that converts a series of command line switches and their values into a hash. It's similar to Get->switches(), but works on any string.
