* Created DRBD->_initialize_drbd() to makes sure the DRBD kernel module can load and tries to build the module, if necessary. This is meant to provide support for clients that can't access needed internet resource (or the internet at all).

Created Storage->get_storage_group_from_path() that takes a block device path and tried to find the Storage Group it belongs to.
Updated Storage->get_storage_group_data() to make it possible to look up a storage group UUID using the SG's name.
Updated DRBD->gather_data() to take a pre-generated XML via the new 'xml' parameter.

* Fixed a bug in anvil-delete-server where, if a server was off already, the server would not be removed from pacemaker.
* WIP - continuing on scan-network

* Updated DRBD->allow_two_primaries() to take the 'set_to' parameter which can be 'yes' to all and 'no' to disallow dual-primary.
* Updated ocf:alteeve:server to call allow_two_primaries() with 'set_to' = 'no' instead of calling 'adjust' after a migration completes.

* DRBD is now configured to a ping-timeout of 3 seconds.
* Created Log->switches() that returnes the command line switches used by Anvil! tool command line calls based on the active log levels / secure logging. Appended this to all invocations of our tools.
* Updated Database->resync_databases() to now only skip 'jobs' and 'variables' tables with less than 10 record differences. All other differences will trigger a resync.
* Created System->_check_anvil_conf() that, as you might guess, checks in anvil.conf exists and created it (using defaults), if not. It also checks to see if the 'admin' group and user exists and creates them, if not.
* Updated anvil-daemon to check anvil.conf on start up and in each loop. Created the function check_journald() that checks (and sets, if needed) that journald logging is persistent.
* Made striker-manage-peers to check_if_configured on the Database->connect() when updating anvil.conf and the target UUID is the local machine. Also created a loop to make the reconnection a lot more robust.

* Created DRBD->check_if_syncsource() and ->check_if_synctarget() that return '1' if the target host is currently SyncSource or SyncTarget for any resource, respectively.
* Updated DRBD->update_global_common() to return the unified-format diff if any changes were made to global-common.conf.
* Created ScanCore->check_health() that returns the health score for a host. Created ->count_servers() that returns the number of servers on a host, how much RAM is used by those servers and, if available, the estimated migration time of the servers. Updated ->check_temperature() to set/clear/return the time that a host has been in a warning or critical temperature state.
* Finished ScanCore->post_scan_analysis_node()!!! It certainly has bugs, and much testing is needed, but the logic is all in place! Oh what a slog that was... It should be far more intelligent than M2 though, once flushed out and tested.
* Created Server->active_migrations() that returns '1' if any servers are in a migration on an Anvil! system. Updated ->migrate_virsh() to record how long a migration took in the "server::migration_duration" variable, which is averaged by ScanCore->count_servers() to estimate migration times.
* Updated scan-drbd to check/update the global-common.conf file's config at the end of a scan.
* Updated ScanCore itself to not scan when in maintenance mode. Also updated it to call 'anvil-safe-start' when ScanCore starts, so long as it is within ten minutes of the host booting.

* Updated DRBD->manage_resource() to call 'drbdadm adjust <res>' when starting a resource to help deal with a periodic issue where the 'allow-two-primary' option on the peer doesn't match the local setting.

* Added the scan-hpacucli scan agent. It's been done for a while and should have been added ages ago.
* Updated anvil-rename-server to get to the point where it will take down the DRBD resources on all machines, but waits if there is a sync under way. It also verifies that the server is off on all systems from virsh's perspective.

* The get_mmeory endpoint was completed.
* The get_replicated_storage endpoint was completed, though it requires testing and likely has issues.
To prepare for the get_status endpoint work, I needed to update ScanCore and modules to track the host_status. This commit contains the work needed for this.
* Updated ScanCore->post_scan_analysis_striker() to use configured fence devices (except PDUs) to check if a target host is off or on, in there is no host_ipmi interface. In all cases, if a machine can be confirmed on or off, the host_status is now updated.
* To support the above fence based power checks, updated scan-cluster to store the on-disk CIB in the new scan_cluster -> scan_cluster_cib colume.
* Updated ScanCore->parse_cib() to map stonith primitive IDs to fence agents. Updated ->parse_crm_mon() to not call if the executable doesn't exist to avoid unhelpful error messages in the logs when called from a Striker.
* Update DRBD->gather_data() to get the size data from /sys/block/drbd<minor>/size' x '/sys/block/drbd<minor>/queue/logical_block_size so it works when a device is Secondary (and can't be promoted).
* Updated Database->get_hosts_info() to record the short host name as well as the stored host name. Created ->update_host_status() as a wrapper to ->insert_or_update_hosts() that only updates the host status.
* Updated anvil-join-anvil to disabled ksm and ksmtuned daemons.
* Updated scancore and anvil-daemon to set the host_status to 'online' on startup.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Fixed a bug in ScanCore->agent_startup() where a (thankfully broken) check to append tables to the 'sys::database::check_tables' would cause an infinite loop as both were pointers to the same anonymous array.
* Fixed a bug in scan-ipmitool where the scan_ipmitool_variables table didn't use a host_uuid reference, causing resyncs of that table to sync for all hosts and cause DB errors when the scan_ipmitool record from another host wasn't sync'ed yet.

* Reworked DRBD->get_next_resource() to pull from the database, and to no longer do that increments-of-three nonsense. Avoidable complexity. Also added a call to Cluster->get_anvil_uuid() if the 'anvil_uuid' parameter wasn't passed.
* Updated Database->get_host_from_uuid() and ->get_hosts() to now take 'include_deleted' parameter and default to not returning deleted hosts. This fixed issues where anvil-{delete,provision}-server calls could assign jobs to now-deleted hosts with reused host names.
* Updated anvil-delete-server to print log entries to STDOUT. Also updated it to not wait of shutdown of a server in pacemaker to complete, and instead to destroy it after calling pacemaker's resource stop. Updated to also check to see if the server being deleted is already out of pacemaker and, if so, skip that step and directly try to destroy the server, if it's running.
* Updated anvil-provision-server to force 'peer_mode' runs to pull their TCP Port and DRBD minor numbers from the job. This fixes a bug where the same resource on two machines could use different TCP ports.

* Finished DRBD->get_next_resource() that returns the next available minor and the next free TCP port (with two free ports available after it).
* Created Storage->get_storage_group_details() that pulls together the LVM, storage group members and storage groups into one block of data.
* Made more progress on tools/anvil-provision-server. It now gets up to the point of creating LVs, creating DRBD resource files, loading them, creating metadata and up'ing the resource. It doesn't yet (successfully) force a new resource to primary.

* Added the anvil.conf option 'sys::privacy::strong' that controls if the Anvil! ever "calls home". Initially, this controls DRBD's usage flag.
* Updated DRBD->get_devices() to track resources by their 'by-res' names as well and by the normal '/dev/drbdX' devices.
* To mitigate https://bugzilla.redhat.com/show_bug.cgi?id=1868467, updated Get->bridges() to parse the normal (non-JSON) data if we get invalid JSON output.
* Updated anvil-join-anvil to not disable, and in fact enable, libvirtd on boot. With DRBD 9, the original fear of a user accidentally booting a VM that's running on the peer no longer is an issue. By enabling it and leaving it on, Striker dashboard users won't lose their virtual machine manager link unless the node powers off. Also enabled actually updating the job progress, completing this tool!

* Created Tools->refresh to reload anvil.conf in one call.
* Created Anvil::Tools::Network to hold network-related tasks.
** Created Network->is_remote() that tests to see if a string (containing a target) refers to the remote machine (versus a local machine). Updated all previous checks to use this new method.
** Moved Get->network_details() and Get->network() to the new Network module. Renamed Get->network() to Network->get_network().
** Made Network->get_ips() work locally and remotely.
** Created Network->find_matches() that compares two scanned machines IPs (via two previous calls to Network->get_ips())
* Created Database->manage_anvil_conf() that will add, update or remove a given database connection in a local or remote anvil.conf file.
* Fixed bugs in Storage->backup() where the bash calls were quite broken. I'm not sure how it ever worked before... x_x
* Updated anvil-daemon to not initialize a database unless it's running on dashboard. Also added a check at the startup of anvil-daemon where it will go into a loop waiting for a database to become available, re-reading anvil.conf each loop.
