 *        'crontab' => array(
 *          'rules' => array('* * * * *'),
 *        ),
 *      ),
 *    - "launcher": (optional) Default launcher (plugin type) for this job.
 *      Example of a job using the serial launcher as default:

 * cron_pre_launch(*)
 * cron_pre_run
 * cron_pre_invoke
 * cron_post_invoke
 * cron_post_run
 * cron_post_launch(*)
 *
 * Depending on how the launcher works, the hook_cron_post_launch() may be
 * invoked before or after hook_cron_post_run() or somewhere in between.
 * An example of this is the Background Process launcher, which launches
 * the job in a separate thread. After the launch, hook_cron_post_launch()
 * is invoked, but the run/invoke hooks are invoked simultaneously in a
 * separate thread.
 *
 * All of these hooks can also be implemented inside a plugin as a method.
