[~Zian Chen], mind to check the failed unit tests as well as checkstyle issues.

> Add unit test to validate queue priority preemption works under node
> partition.
> Test configuration:
> queue A (capacity=50, priority=1)
> queue B (capacity=50, priority=2)
> both have accessible-node-labels set to x
> A.accessible-node-labels.x.capacity = 50
> B.accessible-node-labels.x.capacity = 50
> Along with this pre-emption related properties have been set.
> Test steps:
> - Submit an application A1 to B, with am-container = container = 4096, no.
> of containers = 4
> - Submit an application A2 to A, with am-container = 1024, container = 2048,
> no of containers = (NUM_NM-1)
> - Kill application A1
> - Submit an application A3 to B with am-container=container=5210, no. of
> containers=NUM_NM
> - Expectation is that containers are pre-empted from application A2 to A3
