Feature request: Visible cue when a worker is queued for concurrency

[ecapuano]

I love that default concurrency settings only permit 2 plaso jobs to run at a time, which is reasonable. However, the GUI provides no way to know that this is why a job isn't running. Could we show a status of "Queued" for jobs that are waiting in line?

That's a great idea! I'll see if we can get this from the celery state.
