Fix reschedule crashed Jobs race condition

• Tolerating the exception and release the lock for the time being until the Models behavior can be redesigned.

Kill parent and shutdown on Redis \Throwable

Kill the parent Worker (Job) Process when the Redis Watchdog Process encounters a Redis \Throwable and shutdown the Redis Watchdog process.

In the future it would be good to send a SIGUSR to the parent Worker Process to indicate that the Redis Watchdog Process was registered and it was safe for the Worker Process to proceed using the distributed mutex subsystem.
