* Fixed a bug in Database->_find_behind_databases() _find_behind_databases() where the logic to figure out which column was the host_uuid reference was too liberal, causing the wrong column to be selected in some cases. Also added a check to not look for host_uuid columns on specific tables where a match would be made, but the column is allowed to be null (like server_host_uuid that indicates the host of the server).
* Started work on the scan-filesystems scan agent, which is needed to record the data that the file system UI endpoints will need.
* Removed the 'not null' constraint from 'servers' -> 'server_host_uuid'.
* Fixed a bug in 'anvil-provision-server' where the driver ISO being 'none' caused the provision script to use the driver ISO switch.

* 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.

* 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.

* 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.

* 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.

* 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 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.

* 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.
