implemented graceful shutdown
Dealing with the rogue jobs on shutdown.

Now we wait for a period of time, set the status to inactive and let it die.
This can be tricky if a job is actually taking time, and we mark it inactive
because this job will be executed again, and if it is not idempotent it may
repeat the job.
Setting killed jobs to failed.

Instead of setting to inactive, it may be safer to mark them failed and then retry.
Initial cut of the kue UI for batching.
Removing console logs and refreshing at 1000s
