Description

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.
