Added DB connections to ocf:alteeve:server when starting or stopping
servers. This is to ensure that the servers -> server_state are updated
properly.

* Updated DRBD->manage_resource() to check if the host is StandAlone when asked to 'up' a resource and, if so, connect first. Also updated this to error out gracefully if the call to allow_two_primaries() returns non-zero.
* Update Server->migrate_virsh() to error out gracefully if the DRBD->allow_two_primaries() returns non-zero.

* Updated DRBD->manage_resource() to take the task 'adjust'.
* Updated ocf:alteeve:server's start_drbd_resource() to call adjust if startup of a resource isn't needd.
Signed-off-by: digimer <mkelly@alteeve.ca>
* 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->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.

* 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.

* Adds a "sensitive" DB connection to ocf:alteeve:server when migrating a VM. This is needed so that migrations can be done cold or live, based on servers -> server_live_migration.
This resolves issue #284.

* 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.

* Updated Network->load_ips() to load extra information about the interfaces.
* Updated ocf:alteeve:server to not check libvirtd daemon state on server start.
* Updated scan-hardware to check for duplicate entries and purge if found.
* Updated scan-network to check for the 'default' virbr0 interface by checking if the config file exists instead of calling virsh.
* Updated scan-server to have better logging.
* Created the new (and incomplete) anvil-test-alerts tool
* Updated scancore to support --purge to pass to all agents and then exit.
* Updated ScanCore->call_scan_agents() to no longer use 'timeout' as it was causing issues with virsh calls.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Updated ocf:alteeve:server to always try to bring up the peer's DRBD resource, even when the local resource is up.
* Fixed a bug in scan-network where purging duplicate bridges failed in some cases.

* 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.

* Updated anvil-daemon to have a new function called "handle_special_cases" called during startup that does any weird bug mitigation required. For now, this is used to mitigate against rhbz#1961562, though certainly it will be used for other reasons later.

* Updated Cluster->parse_cib() to not require a database connection (part of the work to make ocf:alteeve:server run without a DB)
* WIP: Continuing work on the ocf:alteeve:server RA to run without database connections.
* Updated the scancore daemon to explcitely check that all scan agent schemas are loaded in all databases on startup. This is to resolve resync issues on rebuilt strikers that may not yet have some schemas loaded when a DB resync runs.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Fixed a problem with Database->insert_or_update_variables() where variable_source_uuid being set to an empty string wasn't converted to NULL.
* Fixed Database->locking() where the way the lock variable was set was rather broken.
* Created Striker->check_httpd_conf() which configured apache to handle the integration of the new WebUI for Anvil! management with the existing WebUI.
* Updated System->update_hosts() to specifically set the 127.0.0.1 and ::1 lines to handle how cloud-init overrides /etc/hosts and breaks CI/CD tests.
* Removed the old index.html as it's now used for the new WebUI.
* Began work on removing DB connection requirements from ocf:alteeve:server.

* Fixed a bug in Database->get_tables_from_schema where history.X and X tables were being stored in the table list.
* Updated ocf:alteeve:server to no do resyncs on DB connect.

* Created Cluster->check_stonith_config() that checks and, if needed, reconfigures a cluster's fencing (stonith) config.
* Updated scan-cluster to call Cluster->check_stonith_config() at the end of each call.

* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Fixed a bug where, in rare cases, $anvil->hostname() would call 'hostnamectl' and get a dbus error during shutdown, which would then cause the hostname to be changed to the error in the database.
* Fixed a bug in Cluster->boot_server() where it would never verify that a server has started successfully.
* Updated Database->get_ip_addresses() to store the IPs we manage in 'ip_addresses::<ip_address_address>::X'.
* Updated ocf:alteeve:server to work from command line calls, though more testing is still needed.
* Started work on 'anvil-rename-server', but haven't gotten far with it yet.

* Updated Cluster->add_server() to now set failure timeouts to actual numbers instead of INFINITY after discovering that INFINITY doesn't work in those cases.
* Updated Databsae->get_hosts to now check if other entries have the same host name, and if so, to set their host_key to 'DELETED'. This should make it easier to handle when a hardware machine is replaced by new hardware but uses the same host_name.
* Updated Email->check_queue() to start and enable postfix.service if it's found to not be running.
* Updated Get->available_resources() to return '!!no_data!!' when a given host hasn't got any data in scan_lvm_vgs. Now use this in anvil-provision-server to exit if a node or dr host hasn't run scancore yet.
* Fixed a bug in scan-lvm where the pvs_uuid wasn't being loaded properly, preventing lost PVs, VGs and LVs from being flagged as deleted.
* Started work on anvil-migate-server, though it's far from complete.

* Fixed a bug in Cluster->parse_cib() when a server that is off wasn't setting 'status'.
* Renamed 'server::location::<server>::host' to '...::host_name' in several places.
* Got more work done on anvil-delete-server, up to the point where it calls the new Cluster->delete_server() method.
* Updated fence_pacemaker to call 'drbdadm adjust all' to dampen an issue where in-memory fence configs seem to change, preventing reconnection of the peer after it reboots from the fence. More testing needed on this issue.

* Removed the exit-if-no-DB check in ocf:alteeve:server so that (hopefully, needs testing), running servers won't be impacted if the nodes lost contact with both/all strikers.
* Updated scan-server to make an explicit check for missing XML definition files on startup and write them if needed.
* Very beginning work on anvil-delete-server has been started.
* Updated anvil-provision-server to wait when it's running in peer mode until the new XML definition is in the DB and then write it out to disk before exiting. Also updated it to add the new server to pacemaker before exiting.

* Started work on Get->available_resources() that will take an 'anvil_uuid' and figure out what resources are still available for use by new servers or that can be added to existing servers.
* Fixed a bug in ScanCore->agent_startup() where tables weren't being generated properly from the agent's SQL file.
* Made Storage->change_mode() return silently if it's called without a mode being passed. This happens frequently and is harmless so it's not worth filling the logs with errors.
* Renamed the 'start_time' key to 'at_start' when recording files' MD5 sums in Storage->record_md5sums and ->check_md5sums.
* When we moved the directory scan logic out of the 'scancore' daemon and into 'Storage->scan_directory', the logic to record scan agent names in 'scancore::agent::<file>' was removed. This broke a few things and, so, it was restored when it was found that a file starts with 'scan-' and the directory matches the scancore agent directory.
* Moved the 'scancore' daemon's 'load_agent_strings' to 'Words'
* Updated Words->parse_banged_string() to look for variables in the format 'value=X:units=Y' and translate it properly.
* Fixed a bug in scan-ipmitool where discovered sensor INSERT SQL queries were queued, but not committed.
* Fixed a bug in scan-storcli where a while loop was broken, preventing execution.
* Fixed a bug in the 'scancore' daemon where it wouldn't exit if sums changed. Fixed a bug where alerts weren't being sent between loops. Fixed a bug where command-line log level wasn't surviving inside the main loop.

* Created (but not finished) scan-apc-pdu
* Added support to tracking maintenance-mode for nodes in Cluster->parse_cib
* Created Remote->read_snmp_oid().

* Updated Server->get_status() to write-out server XML files on-demand.
* Finished scan-cluster.

* Updates servers -> server_host_uuid to drop the 'NOT NULL' constraint.
* Created the new Get->server_uuid_from_name() that does what it says on the tin. Fixed a bug in ->host_uuid_from_name() where the host name was being returned instead of the UUID.

* Updated the servers table to remove the 'not null' constraints on the server_start_after_server_uuid, server_pre_migration_file_uuid and server_post_migration_file_uuid columns.
* Updated ScanCore->agent_startup() to connect to the database(s) when there isn't a table list.
* Updated Server->migrate_virsh() to test for DB access before making DB calls (to allow ocf:alteeve:server to function even if all ScanCore DBs are offline).
* Updated ocf:alteeve:server to connect to the databases (though work without it), and changed '$FILE_NAME' to be 'ocf:alteeve:server' (to make logging more legible)
* Created the skeleton for 'scan-storage'.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.
