> 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.
