> The question "which apps are in queue x" can be asked via the RM REST APIs, through the
ClientRMService, and through the command line.  In all these cases, the question is answered
by scanning through every RMApp and filtering by the app's queue name.
> All schedulers maintain a mapping of queues to applications.  I think it would make more
sense to ask the schedulers which applications are in a given queue. This is what was done
in MR1. This would also have the advantage of allowing a parent queue to return all the applications
on leaf queues under it, and allow queue name aliases, as in the way that "root.default" and
"default" refer to the same queue in the fair scheduler.
