No mechanism to release abandoned blocked jobs

[travismcchesney]

It doesn't seem like there is any mechanism to release blocked jobs that have been abandoned by a scheduler.

I see that there is AbstractRedisStorage#releaseTriggersCron(), but it will only execute if the scheduler has stopped running jobs altogether. The scenario I'm thinking of is if a scheduler has some jobs locked, is then killed (or dies uncleanly), and is brought back up. In this case, the lastTriggersReleaseTime will be up-to-date, and any jobs that are blocked will remain so.

Is this an issue you see as worth addressing, or is there something I'm missing that would pick these up?
