      Description

      Fair scheduler use `QueuePlacementPolicy` to map a request to queue. There are several problems:

      1. The termination of the responsibility chain should bind to the assigning result instead of the rule.
      2. It should provide a reason when rejecting a request.
      3. Still need more useful rules:
        1. RejectNonLeafQueue
        2. RejectDefaultQueue
        3. RejectUsers
        4. RejectQueues
        5. DefaultByUser
