> Add Yarnclient#getDelegationToken API implementation and SecureLogin in router

>             Project: Hadoop YARN
>          Issue Type: New Feature
>          Components: router
>    Affects Versions: 3.1.1
>            Reporter: Xie YiFan
>            Assignee: Xie YiFan

> 1.we use router as proxy to manage multiple cluster which be independent of 
> each other in order to apply unified client. Thus, we implement our 
> customized AMRMProxyPolicy that doesn't broadcast ResourceRequest to other 
> cluster.
> 2.Our production environment need kerberos. But router doesn't support 
> SecureLogin for now.
> https://issues.apache.org/jira/browse/YARN-6539 desn't work. So we 
> improvement it.
> 3.Some framework like oozie would get Token via yarnclient#getDelegationToken 
> which router doesn't support. Our solution is that adding homeCluster to 
> ApplicationSubmissionContextProto & GetDelegationTokenRequestProto. Job would 
> be submitted with specified clusterid so that router knows which cluster to 
> submit this job. Router would get Token from one RM according to specified 
> clusterid when client call getDelegation meanwhile apply some mechanism to 
> save this token in memory.
