* 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.
* Updated ScanCore->agent_startup() to allow for empty scan agent table lists.

* Started work on the new scan-cluster scan agent that will parse out and store data from the pacemaker CIB.

* 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.

* Created Database->insert_or_update_updated() to manage entries in the special 'updated' table.
* Updated Alert->check_alert_sent() to not use the 'type' parameter, but instead use the 'clear' parameter, to be more consistent with other methods.

* 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.

* Created Dataase->check_for_schema() that scancore agents can use to check/load the SQL schema
* Updated Database->write to take the 'transaction' parameter.
* Used scan-hardware as the test mule for scan agent SQL handling.

* Renamed the scan-network skeleton scan agent to scan-hardware and started work on it based on the M2 version.
* Updated Database->get_recipients() to take the 'include_deleted' parameter, and changed the default behaviour to only return active records.
