I agree that FederationInteceptor need more information, I think it is better
to use/add fields in the AM RM allocate protocol. Generally it should figure
out all information by looking at the communication between AM and (home) RM,
e.g. application priority, node label etc.

One concern in adding fields AMRM allocate protocol is then federation
framework will not be able to working with old AM's applications.
Like 2.7.2 version will not have the fields which is required for application
submission to other subclusters.
Better option could be pushing along with ApplicationHomeSubCluster the
application Submission Context too. And let interceptor query when AM
registration happens.
