Thanks for your review and valid suggestions.
It makes sense:
1. I will remove the old auto created leaf deletion related logic.
2. Actually, the event triggered by an edit policy thread, which already a
background thread that periodically checks , i will make it more readable or
just add a new thread.
3. I will handle deletion of ParentQueues.

> It's better if we can delete auto-created queues when they are not in use for
> a period of time (like 5 mins). It will be helpful when we have a large
> number of auto-created queues (e.g. from 500 users), but only a small subset
> of queues are actively used.
