> Have a discussion with [~vinodkv] and [~jianhe]: 
> In existing Capacity Scheduler, all allocation logics of and under LeafQueue are located
in LeafQueue.java in implementation. To make a cleaner scope of LeafQueue, we'd better move
some of them to FiCaSchedulerApp.
> Ideal scope of LeafQueue should be: when a LeafQueue receives some resources from ParentQueue
(like 15% of cluster resource), and it distributes resources to children apps, and it should
be agnostic to internal logic of children apps (like delayed-scheduling, etc.). IAW, LeafQueue
shouldn't decide how application allocating container from given resources.
