This was a simple factory that would give compatibility for the existing client to load up the appropriate auth plugin. A more robust plugin loading mechanism is coming for this and having it available encourages other auth plugins that they should be using that where they shouldn't. Just remove it from the auth plugin class. It shouldn't be used by anyone else so lets keep it on the client objects. Blueprint: plugin-params Change-Id: I0618b646f302300d41c7dd7153a1c0bdc237a745
