> Add a user to groups mapping service

>
> Currently the IPC client sends the UGI which contains the user/group
> information for the Server. However this represents the groups for the user
> on the client-end. The more pertinent mapping from user to groups is actually
> the one seen by the Server. Hence the client should only send the user and we
> should add a 'group mapping service' so that the Server can query it for the
> mapping.
