---------------------------------

[~sunilg] Thanks your jira,  i have a doubt that "creating multiple queues and making
users submit applications to higher priority and lower priority queues separately" in your
doc,it  means  we create multiple queues, e.g. queue A and queue B,then label A  higher priority
queue ,label B lower priority queue, after that ,user can submit higher priority application
to A ?but i look up your code ,it means user can submit different priority application to
same queue and the queue has a default priority,the cluster has a max priority.

> It will be very useful to support priorities among applications within the same queue,
particularly in production scenarios. It allows for finer-grained controls without having
to force admins to create a multitude of queues, plus allows existing applications to continue
using existing queues which are usually part of institutional memory.
