* Created System->wait_on_dnf() which was plucked from anvil-daemon, and now also called in scancore and anvil-safe-start.
* Updated scancore and anvil-safe-start to check on start that DRBD's kernel module is available (and build if not).

* Fixed a bug in System->reboot_needed() where the cache file path had a typo in the hash key.
* Updated anvil-daemon to use the full path to dnf when determining if a dnf process was running.

* Updated Server->shutdown_virsh() to work without a database connection.
* Updated System->reboot_needed() to store/read from a cache file when the database is not available.
* Updated anvil-safe-start to remove the old --enable/disable/status switches, now that we use anvil-safe-start.service systemd unit.
* Reworked anvil-safe-stop to work without a database connection, and to work on DR hosts.
* Updated anvil-special-operations to add new tasks, but it's likely these new tasks aren't needed and will be removed very shortly.
* Added/updated multiple man pages.

* Updated anvil-update-system to reboot a target whose kernel updated using an anvil-manage-power job,
* Started making striker-update-cluster run as a job (not at all complete). Fixed a bug where the wrong IP was being used when finding access to a target.

* Fixed a bug in anvil-safe-stop where it wouldn't trigger a migration when the peer is online.
* Updated anvil-update-system to set job_data to 'failed' and exit with rc 4 if the os update failed.
* Got striker-update-cluster to error out and exit if a called 'anvil-update-system' job failed.

* Updated DRBD->get_status() to take the new 'host' paramter to allow the caller to define the hash key string used in the stored data.
* Updated Get->anvil_version() (and a few other places) to use the new 'striker-ui-api' shell user, replacing the 'apache' user.
* Updated Remote->test_access() to take the new 'close' parameter to close the SSH session used when testing access to the target.
* Fixed a logging bug in anvil-manage-power.
* Updated anvil-update-system to take the '--no-reboot' and 'clear-cache' command line switches.

* Updated Remote->call() to remove the 'background' parameter as it wasn't working.
* Updated anvil-manage-server-storage to use 'anvil-manage-server-storage' to adjust resources in a way that doesn't block.

* Did more work on adding support for adding new disk drives to servers in anvil-manage-server-storage.
* Updated anvil-manage-storage-groups To check for / delete duplicate storage groups with the same name.

* Added logging to anvil-provision-server and anvil-daemon to try to find the cause of jobs being re-run after completing. May have fixed with a fix to job_progress updates going to 100 too early in some cases.

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

* 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 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.

* 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 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.

* Added call to System->configure_logind() to anvil-join-anvil and anvil-version-changes.

* Created Get->virsh_list_net() and Get->virsh_list_os() that call and parse osinfo-query directly to create lists of supported network interfaces and OS optimization options used when provisioning VMs. The later of which is used to replace the old language list of OSes, which was clunky and prone to missing valid options.
* Updated Get->available_resources() to remove the old anvil_dr1_host_uuid mechanism of finding and referencing DR resources.
* Started adding --network support to anvil-provision-server to allow users to specify a specific network bridge, MAC address and model to use for a new VM.

* In Cluster->parse_cib(), added parsers for node attributes and resource rules. Also stored the existence of and details of each under the server resources for easier referencing.
* Updated scan-server to check for / add DRBD fence rules as needed.
Scancore APC agent bugs;
* For clarity, converted all '#!no_value!#' and '#!no_connection!#' to use '!!' instead in APC scan agents.
* Fixed a bug to set/clear alerts related to phases disappearing to deal with concurrent logins from different hosts triggering false phase loss alerts.
* Fixed missing variables not being passed to alerts/log entries.
Started more work on anvil-manage-server, but on hold again while the DRBD fencing work is completed.
