Attaching v1 of the Federation StateStore APIs. The APIs include:
* _FederationMembershipState_ which encapsulates the YARN (sub)clusters that
are participating in Federation.
* _FederationApplicationState_ which is mapping between the Application and
it's home (sub)cluster.
Please refer to the [design
doc|https://issues.apache.org/jira/secure/attachment/12733292/Yarn_federation_design_v1.pdf]
in the parent JIRA (YARN-2915) for further details.
