With this new system, a 'primary_db' is chosen (first connected DB UUID when sorted) and only it does resyncs. Further, resyncs have been pulled from all tools except anvil-daemon. So with this new system, the chances of duplicate, simultaneous resyncs should be removed (hopefully for real this time).
* Database->check_agent_data() no longer calls a resync after loading a
schema.
* Removed the Database->coonnect() 'all' parameter
* The database used to read from is now always the same as the primary,
even if there is a local DB.
* Database->connect() 'check_for_resync' parameter can now be set to
'2', which means "check for resync _if_ I am primary", where '1' still
checks for resync no matter what.

* Updated Database->get_jobs() to take 'job_host_uuid = all' to allow
loading jobs from all cluster machines. Also updated it to record the
'job_host_uuid' and the unix timestamp version of 'modified_date'.

* Switched all calls to virsh to use Sys::Virt to deal with contention of simultaneous virsh calls.
* Removed collecting screenshots from scan-server.
* Fixed a bad variable substitution in an alert.
* Fixed a bug where a server's boot time wasn't being recorded properly.
* Reworked how we determine which server definition was most recently updated and propogated.

* Updated the pcs wrapper to flock anything but status calls.
* Updated scan-apc-pdu to purge regardless of the host it's called on any host.
* Fixed a bug striker-purge-target that wouldn't purge anvil nodes in various cases.

* Hit a bug where a server's definition file was written to disk while not being valid. Added logging in case it happens again, and additional safe-guards to help avoid it from recurring.

* 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 Cluster->recover_server() to set the desired recovery state before calling the crm_resource refresh.
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.
Signed-off-by: digimer <mkelly@alteeve.ca>
* 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.

* 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 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.

* 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.

* Created DRBD->check_proxy_license() to do (some level of) sanity checks on the DRBD proxy license file.
* Updated DRBD->gather_data() to parse out the inside and outside ports for resource configs using proxy.
* Reworked DRBD->get_next_resource() to return 1, 3 or 7 TCP ports depending, with the new long_throw_ports parameter triggering the 7 ports.
* Added 'tcpdump' to the anvil-core requires list.
* Reworked scan-drbd to record the ports used in proxy configs. This required adding a check to change the 'scan_drbd_peer_tcp_port' column type to 'text' to support CSVs.
* Reworked anvil-manage-dr (needs testing!) to support "long-throw" DR configs.
* Updated anvil-safe-stop to check if the nodes are in the cluster before trying to migrate.

* Reworked Network->bridge_info() to use 'ip' to get the list of bridges, and 'bridge' to find interfaces connected to the bridge.
* Added 'test' messages to Words->string().
* Fixed a bug in scan-lvm where mdadm based PVs didn't read the sector size properly.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Fixed a bug in scancore-agents/Makefile.am where scan-network was missing.
* Started work on anvil-delete-server.8. Incomplete at this time.
* Updated Network->get_ips() to record the interface status.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Added multiple new private methods to Network that help in managing the firewall.
* Updated Server->boot_server to manage the firewall after the server boots. Updated ->migrate_server to create a job, if a database connection exists, for the migration target to update it's firewall as soon after the server appears as possible.
* Updated ocf:server:alteeve to manage the firewall when called post-migration, in case there was no DB connection and the job above didn't run. Fixed a bug where the disk state wasn't being evaluated properly.
* Updated scan-server to check that the firewall is managed when a server state has changed.
* Updated anvil-daemon to run Network->manage_firewall on startup.
* Heavily reworked 'anvil-manage-server' to either just run 'Network->manage_firewall', or if passed '--server X', to wait for the server to appear for up to 1 minute, then to check that the firewall is managed (to capture servers being migrated to the host.)
* Removed firewall management from striker-prep-database.
