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 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.

* 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 ScanCore->agent_shutdown() that writes out the time the scan agent last ran, and how many databases were available when it last ran.
* Updated ScanCore->agent_startup() to read the the last run data created above.
* Updated Database->connect() to set 'sys::database::last_db_count' to the scan agent's recorded last DB count.
* Updated all agents to call ScanCore->agent_shutdown() at the end of their run.

* WIP - Continuing work on the new anvil-manage-server tool.
* Updated Database->get_anvils() to load information on the files available on each Anvil! system.
* Updated Database->insert_or_update_network_interfaces() to no longer take the 'timestamp' parameter.
* Removed all logging from Database->refresh_timestamp() to speed it up, given how often it will be called now.

* Bumped scancore's scan delay from 30 seconds to 60.
* Shorted the age-out time to 24 hours and again boosted the archive thresholds. As we get a feel for the amount of data collected on multi-Anvil! systems over time, we may continue to tune this.l
* Moved Database->archive_database() to be called daily by anvil-daemon, instead of during '->connect' calls.
* Added locking to Database->_age_out_data to avoid resyncs mid-purge. Also moved the power, temperature and ip_address columns into the same 'to_clean' hash as it was duplicate logic.

* Updated the scan agent timeout to 60 seconds. Also made the scan agent exit code log entries more helpful.
* Updated System->collect_ipmi_data() to now better handle duplicate sensor names. Now, instead of simply appending an integer, we find the hex address and use that in the sensor name when duplicates exist. This solves the problem of the sensor names not being consistently shown in order.
* Fixed message bugs (bad variable insertions) in scan-apc-pdu and scan-apc-ups.
* Fixed schema procedure bugs in the 'temperature' and 'ip_address' tables where the columns were in bad order, causing constanty updates.
Incomplete work;
* Create the shell of 'anvil-manage-storage', but virtually no logic exists in it yet.
* Started work on anvil-safe-start to deal with an issue where DRBD resources don't start when a server is running on a peer.

* Reworked scan-ipimitool so that on nodes and dr hosts, it only scans itself. On strikers, it scans all hosts found in active Anvil! systems with a host_ipmi entry. `
* For all agents, reduced log verbosity to not push too much noise into anvil.log while scancore is running in the background.

* 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 Database->get_power() that loads data from the special 'power' table.
* Fixed a bug in calls to Network->ping() where some weren't formatted properly for receiving two string variables.
* Updated Database->get_anvils() to record the machine types when recording host information.
* Updated Database->get_hosts_info() to also load the 'host_ipmi' column.
* Updated Database->get_upses() to store the link to the 'power' -> 'power_uuid', when available.
* Created ScanCore->call_scan_agents() that does the work of actually calling scan agents, moving the logic out from the scancore daemon.
* Created ScanCore->check_power() that takes a host and the anvil it is in and returns if it's on batteries or not. If it is, the time on batteries and estimate hold-up time is returned. If not, the highest charge percentage is returned.
* Created ScanCore->post_scan_analysis() that is a wrapper for calling the new ->post_scan_analysis_dr(), ->post_scan_analysis_node() and ->post_scan_analysis_striker(). Of which, _dr and _node are still empty, but _striker is complete.
** ->post_scan_analysis_striker() is complete. It now boots a node after a power loss if the UPSes powering it are OK (at least one has mains power, and the main-powered UPS(es) have reached the minimum charge percentage). If it's thermal, IPMI is called and so long as at least one thermal sensor is found and it/they are all OK, it is booted. For now, M2's thermal reboot delay logic hasn't been replicated, as it added a lot of complexity and didn't prove practically useful.
* Created System->collect_ipmi_data() and moved 'scan_ipmitool's ipmitool call and parse into that method. This was done to allow ScanCore->post_scan_analysis_striker() to also call IPMI on a remote machine during thermal down events without reimplementing the logic.
* Updated scan-ipmitool to only record temperature data for data collected locally. Also renamed 'machine' variables and hash keys to 'host_name' to clarify what is being stored.
* Updated scancore to clear the 'system::stop_reason' variable.
* Added missing packages to striker-manage-install-target.

* Updated Alert->register() to take message variables using the 'variables' parameter.
* Added a 'cache' parameter to Database->insert_or_update_health() and ->insert_or_update_temperature(). When set, the SQL UPDATE/INSERT calls and pushed into the array reference set in 'cache'. This is to allow performance improvements when processing a large amount of sensor/device data.
* Updated Log->variables() to take a 'prefix' parameter that, when set, will prefix the string to each variable line.
* Updated scan-ipmitool to use Database->insert_or_update_health() and ->insert_or_update_temperature().

* Fixed a bug if Get->free_memory() where host_type was still being called from the old System->host_type method.
* Added global support for '--log-secure' and '--log-db' switches to enable logging of secure data and DB transactions, respectively.
* Created Database->get_tables_from_schema() that parses a SQL schema file and returns an array reference of tables found, in the order they were found.
* Updated ScanCore->agent_startup() to no longer require manually defining database tables, using Database->get_tables_from_schema() when not manually set.. Updated all existing agents to use this.

* Fixed a bug in Database->insert_or_update_power() where the check to see if 'power_ups_uuid' was passed in was reversed. Also fixed a bug where the convertion of the value to TRUE/FALSE for the old value wasn't being set correctly.
* Updated Server->get_definition() to only translate the host name to a uuid if the host uuid wasn't passed in. Added a sanity check on the UUID as well.
* Cleaned up how existing UPSes are displayed in Striker when managing UPSes. Also renamed the form's scan agents to match the real agent names.
* Fixed alert sorting in scan-apc-pdu.
