* In DRBD->get_next_resource(), implemented a "hold" system where the DRBD minor and TCP port(s) returned are marked as being held for one minute. So subsequent calls won't use the same numbers.
* In anvil-daemon, added a check in run_jobs() where only one instance of a given job command will be started per 2-second loop. This should help reduce the chance of simultaneous race confitions in general.
* Removed from anvil-provision-server and most other tools the call to Job->get_job_uuid(). If the program is called without the job_uuid, don't try to find it. This allows a human (or script) to make repeated calls to a program without one of those calls running a pending job instead.

* Adds support for 'anvil_resources:🐏:reserved' that can be set to a number of MiB to override the default 8192.
* Adds support for 'anvil::<anvil_uuid>::resources:🐏:reserved' to allow for per-Anvil! node override on the reserved RAM default, and over the 'anvil_resources:🐏:reserved' option.

* Updated (not not yet completed) scan-cluster's check_resources() function to check if a FAILED server is ready to try to recover.

* Fixed a bug where servers protected by DR hosts aren't deleted when the server itself is deleted.
* Updated DRBD->delete_resource() to remove the server's XML file if the host is a DR host.
* Updated anvil-version-change and anvil.sql to enable update_audits and the audits table.

* Got more work done on anvil-manage-server-storage; Now shows DRBD resource size, backing LV and size, and calculates/displayes metadata size.

* Updated DRBD->parse_resource() to add references to a resource name and volume for a given backing disk.
* Comtinued work on anvil-manage-server-storage.

* Created the new Database->get_lvm_data to compile LVM data from scan-lvm
* Updated DRBD->parse_resource to call Database->get_lvm_data if needed, and to track backing devices to Storage Groups.

* Updated Database->get_file_locations() to record files available on Anvil! nodes by tracking hosts in Anvil! systems (needed after reworking how DR hosts are linked).
* Updated Get->available_resources() to call Database->get_files() and ->get_file_locations() to restore tracking files available on Anvil! nodes.
* Fixed a couple display bugs in anvil-provision-server when called with --ci-test --options.
* Continued work on anvil-manage-server-storage.

* Updated anvil-manage-server-storage to the point where it can now insert and eject optical disks!
* Updated System->call to log parameters if 'shell_call' isn't set.
* Fixed a bug in anvil-manage-server process_interactive where an $anvil->data reference was being scoped.

* Created Database->track_files() as a dedicated method as trying to verify the existence of file_locations during Database->load_anvils() was fragile and prone to recursive loops.
* Updated Database->insert_or_update_file_locations() to take an anvil_uuid and recursively call for each host, to maintain compatibility with the old ways, and make it simpler to add an entry for both sub-nodes in an Anvil!.
* Created Storage->push_file() that takes a file and rsync's it to all other machines, or creates a job for the file to be pulled if the target can't be accessed.
* Updated anvil-manage-files and anvil-sync-shared to use the new Storage->push_files and Database->track_files methods.

* To update file handling for the new DR host linking mechanism, file_locations -> file_location_anvil_uuid was changed to file_location_host_uuid.
This required a fair number of changes elsewhere to handle this, with a particular noted change to Database->get_anvils() to look at host_uuid's for the subnodes in an Anvil! and, if either is marked as needing a file, make sure the peer is as well. Similarly, any linked DRs are set to have the file as well.
* Created a new Network->find_access that simply takes a target host name or UUID, and it returns a list of networks and IPs that the target can be accessed by.
* Updated Network->load_ips() to find the network interface being used for traffic so that things like the interface speed can be recorded, even when an IP is on a bridge or bond.
Unrelated, but in this commit, is a restoration of calling scan agents with a timeout now that the virsh hang issue has been resolved.

* Created DRBD->parse_resource() to pass a specific DRBD resource's XML data.
* Fixed a bug in Get->available_resources() so that if the threads is lower than CPU cores, the cores are used as the total available to VMs.
* Fixed bugs in Get->server_from_switch() where it just wasn't working properly.
* Updated scan_drbd to not reset a resource's size to 0-bytes when a resource goes offline.

* Updated the storage_group_members table to add the 'storage_group_member_note' that can be set to 'DELETED' to track when a member is deleted. Updated anvil-version-changes to check for and add this column as needed. Updated the anvil.sql schema for the same.
* Updated Cluster->insert_or_update_storage_group_members to add the new column.

* Created Database->get_anvil_uuid_from_string(), Database->get_host_uuid_from_string() and Database->get_server_uuid_from_string() to simplify the process of converting --anvil <string>, --host <string> and --server <string> respectively.
* Fixed bugs in Database->get_dr_links() and Database->insert_or_update_dr_links().
* Updated Database->insert_or_update_states() to make direct calls to hosts instead of using get_hosts to drop out if a host_uuid doesn't yet exist in a DB.

* Adds a "sensitive" DB connection to ocf:alteeve:server when migrating a VM. This is needed so that migrations can be done cold or live, based on servers -> server_live_migration.
