[~zhengchenyu] I have understood what you mean, it is a good design for me, but 
I still hope to provide the design doc of YARN-11154 first, and describe how 
the router uses proxyserver, because YARN-11153 and YARN-11154 are essentially 
the same thing , it's better to complete it in the same pr, this split way 
makes me have some misunderstandings.Thanks again!

> I setup a yarn federation cluster, I can't connect the running app web, but 
> the completed and accepted app's web works.
> So I think need two step: 
> (a) make proxy server support federation.
> (b) make router support proxy server.
> Though it is a not difficult problem, but not easy to describe the problem. 
> So I submit a document YARN-10775-design-doc.001.pdf to explain this.
>  
> If standalone proxyserver is enable, after step (a), the problem is solved.
> If standalone proxyserver is disable, after step (a) and (b), we use router 
> as web proxy server, so we hide the cluster info for client, I think it is 
> reasonable.
