Uploading CS changes.
Hi [~leftnoteasy]
YARN-2004 need to have some changes in CS and LeafQueue. But same methods dummy impl is added in YARN-2003. Hence it will be dependable with YARN-2003, but not opposite. Kindly share your opinion.

> Based on the priority of the application, Capacity Scheduler should be able to give preference to application while doing scheduling.
> Comparator<FiCaSchedulerApp> applicationComparator can be changed as below.
> 1. Check for Application priority. If priority is available, then return the highest priority job.
> 2. Otherwise continue with existing logic such as App ID comparison and then TimeStamp comparison.
