Wangda Tan updated YARN-3356:
-----------------------------
    Description: 
Simliar to YARN-3099, Capacity Scheduler's LeafQueue.User/FiCaSchedulerApp 
should use ResourceRequest to track resource-usage/pending by label for better 
resource tracking and preemption.

And also, when application's pending resource changed (container allocated, app 
completed, moved, etc.), we need update ResourceUsage of queue hierarchies.
