    Make passing user token to registry configurable
    
    This patch adds CONF.use_user_token as a config option. When true, glance will
    continue to use the user token when communicating with glance registry. When
    false, glance will read admin credentials from the config and use those to
    communicate with glance registry. Using admin credentials allow for
    reauthentication when tokens expire and prevents requests from silently failing.
