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

Thanks Karthik and Jian He for review. I will update the patch.
bq. In RMActiveServices, some are using rmContext#setter, some are using activeServiceContext#setter,
we may make it consistent to use the latter
RMContext has 5 setter methods. I used those methods to set from RMActiveService just to retain
interface implementation.

But it misses out clearing RMcontext apps/nodes details and ClusterMetrics and QueueMetrics.
This causes application recovery to fail.
