Description

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 Admin 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.
