> 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.
