> 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.
