Loader job action to clear a job stuck in the Started state

If a job is started but something happens and it exits without updating the status, it is stuck in the starting state in the loader log, and won't start again until restart (or until it gets reset in 10 minutes?). It would be good to clear out the state so it can restart normally, without needing to restart the whole daemon, or doing sql manipulation to clear out the stuck job from the log.

Something available in the API and WS as well as the UI would be good for more options.
