> 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.
