Clean up old worker data

[cggaurav]

So we have had workers run a while ago and we would like to clear up data on our MongoDB storage with worker data that is say over a month.

I'm not exactly sure what the question/issue is? This also sounds like maybe it's an issue with Agenda itself and not the dashboard.

If that's the case please open an issue here and close the one.
