Fix Version/s: 0.23.1
Release Note:Fixed the way head-room is allocated to applications by CapacityScheduler so that it deducts current-usage per user and not per-application.
With multiple jobs submitted per user, and multiple users submitting jobs - the headroom reported to the AppMasters is incorrect (very high).
Leads to a deadlock - reduces started, map tasks not complete... and reduces are not preempted by the AM due to the incorrect headroom.
