Patch updated.I was reusing a class 'ProtoBase' which unfortunately got moved to different
package in the last few hours :) causing my previous patch to fail.

> The history server needs an admin interface with the ability to
> 1. refresh the super user groups configurations,
> 2. refresh user to group mappings,
> 3. refresh its admin acls,
> 4. get groups given a username 
> without requiring a restart of the history server.  This is analogous to the  -refreshSuperUserGroupsConfiguration
capabilities provided by hdfs dfsadmin and yarn rmadmin.
