> Currently {{ApplicationClientProtocol#updateApplicationPriority()}} API returns empty
UpdateApplicationPriorityResponse response.
> But RM update priority to the cluster.max-priority if the given priority is greater than
cluster.max-priority. In this scenarios, need to intimate back to client that updated priority
rather just keeping quite where client assumes that given priority itself is taken.
> During application submission also has same scenario can happen, but I feel when
> explicitly invoke via ApplicationClientProtocol#updateApplicationPriority(), response
should have updated priority in response.
