Thanks [~subru] for the feedbacks.
* Done.
* I opened YARN-6539, I will update in the next patch.
* Done.
* Done.
* Done.
* Done.
* The 2 chains have different objects. Refactoring and Reusing will add additional complexity to the code and it may reduce the stability. I tested this code for long time.
* Done.
* There is no a double translation.
* Done.
* I opened YARN-6537 to track this.
* Moved to a yarn-server-common. I add in the pom.xml in nodemanager and router the test-dependency on it. Right now it has the version dependency, I did not find a way to avoid it.
* Done.
* I added comments to avoid confusions.
* test1, test2 are the names of UGIs.

> Project: Hadoop YARN
> Issue Type: Sub-task

> 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 ApplicationClientProtocol 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.
