------------------------------------------------------------
Attaching initial patch.
* Modified the {{TestAMRMClient}} testcase to refactor out some common code to
a separate class.
* The test uses the asyncAMRMClient, since that way both the async client and
the normal client will be tested, since the async client uses the normal client
internally.
* The general flow is, if the {{PlacementProcessor}} is enabled, the client has
to call {{addPlacecmentConstraint}} before registering with the RM. The client
can then use {{addSchedulingRequests(Collection<SchedulingRequest>)}} to add a
collection of scheduling requests. All scheduling requests in the collection
are guaranteed to be sent in the same allocate call.
* The patch also has some minor bug fixes to ensure end 2 end, things work fine.
