Since we shouldn't require contrib resources to be installed in order to generate documentation, this adds an exception to the plugin loader so that it doesn't try to load the setup.py files that can be found inside each plugin directory inside contrib/ Closes-Bug: 1403897 Change-Id: Id6ece4379599925dd17d22cef401c8d667a0ac51
