* 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.

* Began (but haven't finished) Database->insert_or_update_servers().
* Created Storage->get_file_stats() to collect the (l)stat information for a file.
* Got more work done on scan-server.

* 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.

* 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.

* Created 'Cluster->which_node' that returns 'node1' or 'node2' to indicate which node a host is.
* Continued working on scan_cluster; decided to make it not host-dependent.

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

* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Got scancore scanning the agents directory, and properly holding on startup until at least one database is available (instead of exiting), and holding on startup until the local system is configured.
* Created the skeleton of the first scan agent; scan-network.
* Fixed a bug in Storage->check_md5sums() where dynamically loaded modules, loaded after the initial md5sum calcs, would cause the calling daemon to exit (possibly on every invocation).
* Created the scancore.README that will eventually be the main scan agent guide / API document.
