---------------------------------
Attachment: YARN-3672-YARN-2915-v1.patch
Attaching a first version of FederationStateStoreFacade which is an utility
wrapper that provides singleton access to the Federation state store. It
abstracts out retries and in addition, it also implements the caching for
various objects.
This is also required by the proxy provider in YARN-3673 to connect to multiple
RMs (subclusters).
