    Description

      According to design doc attached in YARN-3214, we need implement following logic in CapacityScheduler:
      1) When allocate a resource request with no node-label specified, it should get preferentially allocated to node without labels.

      2) When there're some available resource in a node with label, they can be used by applications with following order:

      • Applications under queues which can access the label and ask for same labeled resource.
      • Applications under queues which can access the label and ask for non-labeled resource.
      • Applications under queues cannot access the label and ask for non-labeled resource.

      3) Expose necessary information that can be used by preemption policy to make preemption decisions.
