* Fixed a small logging bug in DRBD->allow_two_primaries().
* Updated Database->get_jobs() to record jobs sorted by modified_date so that jobs can be run in the order they were recorded.
* Updated anvil-daemon to track which commands need to be run, and when two or more of the same command need to be run, they're run serially, with each subsequent run starting after the previous one completes.

* Updated DRBD->manage_resource() to set allow-two-primaries=no when up'ing a resource (as no migration can be in progress during an up command).
* Updated scan-drbd to look for StandAlone resources and call DRBD->manage_resource({task = 'up'}) if a connection to a peer node is StandAlone or if the local disk state is detached.

* Updated DRBD->delete_resource() to call scan-drbd and scan-lvm to ensure that the database is updated with the newly freed resources.
* Updated anvil-delete-server and anvil-provision-server to call select scan agents to ensure freed resources are immediately recorded.

* Updated Cluster->recover_server() to set the desired recovery state before calling the crm_resource refresh.

* Updated DRBD->get_status() to attempt to recompile the drbd kernel module if the drbdsetup status fails. If it continues to fail, it exits gracefully now.
* Updated ocf:alteeve:server to test access over a given IP before calling Server->find to avoid timeouts when the peer is down. Also updated it to set the constraints to keep the server on the new host when the old host returns to the cluster.
* Fixed a bug in scan-cluster where a server that is FAILED but not running is now properly recovered.

* Fixed a bug in anvil-version-changes where update_file_location_ready() needed to be called before update_file_locations().
* Added a bit more logging for future debugging.

* 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.

* Fixed a bug in Get->available_resources() where DELETED servers were being counted in the used resources math.

* 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.
