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

Thanks [~curino] for the feedback.
I attached v2 - It reduces the code from DefaultRequestInterceptorREST and fixes the new junit
tests.

> As detailed in the proposal in the umbrella JIRA, we are introducing a new component
that routes client request to appropriate ResourceManager(s). This JIRA tracks the creation
of a proxy for ResourceManager REST API in the Router. This provides a placeholder for:
> 1) throttling mis-behaving clients (YARN-1546)
> 3) mask the access to multiple RMs (YARN-3659)
> We are planning to follow the interceptor pattern like we did in YARN-2884 to generalize
the approach and have only dynamically coupling for Federation.
