Description

HADOOP-11207 adds support for proxy users to perform delegation-token management operations and YARN uses them.

HDFS didn't need them because the doAs functionality is explicitly implemented in webHDFS (JspHelper.getUGI()) - this should be changed to use the common code to avoid duplication.
