Updates our example config file so that it includes configuration settings for the auth_token middleware. A step towards using cinder.conf instead of the api-paste.ini config file for authtoken configuration. Once https://review.openstack.org/#/c/52259/ lands I'll push another review which removes the settings from api-paste.ini (which takes priority).
