> 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.
