AMRMClientImpl does not update AMRM token properly

      Description

      AMRMClientImpl.updateAMRMToken updates the token service before storing it to the credentials, so the token is mapped using the newly updated service rather than the empty service that was used when the RM created the original AMRM token. This leads to two AMRM tokens in the credentials and can still fail if the AMRMTokenSelector picks the wrong one.

      In addition the AMRMClientImpl grabs the login user rather than the current user when security is enabled, so it's likely the UGI being updated is not the UGI that will be used when reconnecting to the RM.

      The end result is that AMs can fail with invalid token errors when trying to reconnect to an RM after a new AMRM secret has been activated.
