HIVE-28209: Allow the use of a proxy user (apache#5233)

* HIVE-28209 Allow the use of a proxy user The log message indicates that `HADOOP_PROXY_USER` is set, but then doesn't allow its use by calling `getRealUser()` which will be `null`. This change allows delegation for HiveMetaStore connections. * Use getRealUserOrSelf from more recent Hadoop --------- Co-authored-by: Steve Vaughan Jr <[email protected]>
