Update `user show` for Identity V3 to account for a domain argument, in doing so, also update `find resource` to be more flexible by allowing **kwargs. Also update `group show` and `project show` since they follow the same logic as a user within a group. Change-Id: Ib828e4dbeb0bd31164396069ce8a64c873179779 Closes-Bug: #1378165
