> Show renewer information in {{DelegationTokenIdentifier#toString}}. Currently 
> {{org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenIdentifier}}
>  didn't show the renewer information. It will be very useful to have renewer 
> information to debug security related issue. Because the renewer will be 
> filtered by "hadoop.security.auth_to_local", it will be helpful to show the 
> real renewer info after applying the rules.
