Description

If the router receives an operation from a proxyUser, it drops the realUser in the UGI and makes the routerUser the realUser for the operation that goes to the namenode.

In the namenode UGI logs, we'd like the ability to know the original realUser.

The router should propagate the realUser from the client call as part of the callerContext.
