* Updated Server->migrate_virsh() to set 'servers' -> 'server_state' to 'migrating' and clear it again once the migation completes. Also added support for cold (frozen) versus live migrations.
* Updated Cluster->parse_cib() to check if a server with the server_state set to 'migrating' isn't actually migrating anymore and, if not, to clear that state. This is needed as scan-server will blindly ignore/skip any migrating server, and if a migration call is interrupted, the state could get stuck.
* Updated the 'servers' database table (and associated Database methods) to add columns for;
** server_ram_in_use - tracking RAM used by a running server
** server_configured_ram - RAM allocated to a running server (used with the above to alert a user and track _currently_ available RAM)
** server_updated_by_user - To be set by Striker tools to indicate when the user made a change that needs to push out to nodes / running server.
** server_boot_time - Tracks the unixtime when the server booted (to track uptime even if the server migrates across nodes).
* Created Get->anvil_name_from_uuid() to easily convert an Anvil! UUID into a name. Also created ->host_uuid_from_name() to translate a host name into a host UUID.
* Created Server->get_runtime() that translates a server name into a process ID and then uses that to determine how long (in seconds) it has been running. This is used when a server transitions from 'shut off' to 'running' to determine exactly when the server booted (current time - runtime).
* Renamed all 'Server->parse_definition' calls that used 'from_memory' to 'from_virsh' to clarify the data source.
* Made scan-hardware smarter about RAM change alerts.
* Updated scancore to load agent strings on startup so that processing pending alerts works properly.

* Did more work on parsing server data out of the CIB. There is still an issue with determining which node currently hosts a resource, however.
* Renamed Server->boot to ->boot_virsh, ->shutdown to ->shutdown_virsh and ->migrate to ->migrate_virsh to clarify that these methods work on the raw virsh calls, outside of pacemaker (indeed, they are what the pacemaker RA uses to do what pacemaker asks).
* Got more work done on the scan-cluster SA.
* Created the empty files for the pending scan-server SA.

* Created 'Cluster->which_node' that returns 'node1' or 'node2' to indicate which node a host is.
* Continued working on scan_cluster; decided to make it not host-dependent.

* Fixed a bug in Server->get_status() where the call to Storage->rsync's returned output checked for '!!errer!!' instead of '!!error!!'.
* Fixed a bug in Storage->rsync where, when no port was passed in, it would try to specify an empty port and fail.

* Converted most 'eval { }' calls to localize $@ and test the output of the eval, instead of checking to see if $@ was set.
* Converted all 'local' hash references to instead use the short host name of the local machine as a new standard.

* 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 Cluster->get_peers() that figures out who the peer node (and DR host, if applicable) are.
* Updated Cluster->parse_cib() to dig out more information.
* Created Cluster->start_cluster() to start pacemaker (via pcsd) locally or on all (both) nodes.
* Started working on ocf:alteeve:server to start/stop the libvirtd/drbd daemons as needed, instead of having pacemaker do it.
* Got more work done on anvil-join-anvil. Node 2 now waits for the cluster to start, and node 1 will do setup as needed, then wait for the cluster to start as well.

* Updated 'variables' -> 'variable_source_uuid' to type 'uuid' and removed the 'not null' constraint.
* Updated Database->insert_or_update_variables() to check/update 'variables_source_table' and 'variables_source_uuid'.
* Created the 'trusts' database table which will, when done, tell anvil-daemon which users@machines to trust (setup passwordkess SSH).
* Created (but not finished) System->manage_authorized_keys() and moved the logic over to it from anvil-daemon.
* Changed the host types "dashboard" to "striker".
* Moved the following methods from 'System' to 'Get';
** System->get_host_type to Get->host_type
** System->get_bridges to Get->bridges
** System->get_free_memory to Get->free_memory
** System->get_os_type to Get->os_type
** System->get_uptime to Get->uptime
* Updated striker to include the host_uuid for the 'node1', 'node2' and (if chosen) 'dr1' when running a job manifest.

* Created Database->insert_or_update_bridge_interfaces() to handle updating the new bridge_interfaces database table that records which network interfaces are connected to which bridges.
* Added 'bridge_mac' and 'bridge_mtu' to the 'bridges' table.
* Started Server->map_network which will, eventually, try to map MAC addresses to IPs and record server -> vnetX -> bridge data. Made getting a server status target-dependent.
* Worked on anvil-update-states to parse and record bridge data.

* Created tools/anvil-check-memory to report how much RAM is used by a given program.
* Added documentation for some previously undocumented methods.
* Updated Database->archive_database() to take the 'tables' parameter.
* Updated Storage->scan_directory() to record a directory's mode and type, even when recursive isn't used.
* Finished System->check_memory().
* Updated ocf:alteeve:server to now NOT stop a DRBD resource unless 'stop_drbd_resources'.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Created DRBD->allow_two_primaries() and ->reload_defaults() that enables (and resets/disables) dual-primary operation (allow-two-primaries=yes), used to enable live migration.
* Created Remote->test_access() that simply verifies that a remote target can be accessed (as a given user).
* Created Server->migrate() that actually migrates a server. It can push already, and pull will be added next.

* Modified Server->boot() to now only work locally. Also updated it to optionally take the XML definition path for the server to boot.

* Created Server->boot() that starts a server and verifies that it did actually start.
* Got ocf:anvil:server smarter about starting DRBD resources, properly handing resources where auto-promote isn't enabled. The 'start' process is now complete (baring bugs).

* Updated DRBD->get_devices() to store data all under 'drbd::config::<host>::x'.
* Created Server->find() that takes a target and collects the servers running on it.
* Updated System->check_storage() to redirect all calls STDERR to /dev/null to supress errors about failing to open /dev/drbdX when LVM's filter isn't setup.

* Created System->active_lv() that, surprise, activates an inactive logical volume. Also created ->check_storage() that parses out the LVM data.
* Fixed a bug in tools/fence_pacemaker that was preventing it from compiling and running.
* Updated ocf:alteeve:server to validate the target server's storage.

* Got Server->get_status() and ->_parse_definition() pulling out all but the device bus data from the XML files. Under devices, started parsing, with 'channel' devices now being parsed.
* Fixed a bug in several Storage->X calls where the test to see if a 'target' was the local host or not wasn't smart enough.
* Purged 'ocs:alteeve:server' to prepare for the rewrite where a lot of the logic is being moved into the Anvil::Tools modules as their functionality will be needed elsewhere anyway.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Started a re-write of the ocf:alteeve:server resource agent. It has bugs and is missing logic, and trying to clean it up given most of the bugs come from trying to clean up the original agent doesn't make sense. Moving much of the logic into module methods as the functions will be needed elsewhere anyway.

* Currently, tools/anvil-update-states is broken while working on the above issue.
* Reworked the jobs table and removed the units/anvil-jobs.service unit. Jobs will be invoked and backgrounded in all calls.
* Started adding missing hidden form fields.
* Updated the 'server' OCF resource agent version and metadata.

** Fixed a bug so that when the agent is invoked on the target node after a migration, it just does a quick check to see if the server is running and exists 0 if so.
