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.
