What did we do

• Created an array of database credentials instead of using define's from wp-config.php, added a hook to change it.
• Modifed the job runner to minimize database connections. The runner now waits until workers are available.
• Modified the construct of the Runner. Hooks are now loaded first, to allow for max workers hook.
• Removed the out of workers message.
• Minimized and humanized the log output, added a debug mode to show all the expanded information.

Hooks added

• Runner.initialize.options - Modify an options array. Used to modify the maximum number of workers and active the debug mode. Has 2 keys: max_workers => int (default 4), debug_mode => bool (default false).
• Runner.connect_to_db.credentials - Modify a database credentials array. Has 2 keys: username => string, password => string.

Planned

• Include another file besides wp-config.php to leave the wp-config.php native.
• Modify the Cavalcade plugin to override all wordpress cron functions.
• Modify the linux service and error handling to minimize interaction with the runner
