It should register it after you load it, via keystonauth1.loading.load_auth_plugin_from_conf_options()
There are also register_auth_conf_options() and get_auth_plugin_conf_options,  which I think are mainly used 
for listing the most used plugins' options in the debug log. But I don't think it would be wise
just to choose a plugin and register its options for auth_url, because it is ugly, I think, and can lead to
other problems.

It's not just Mistral, but every component which uses keystonemiddleware.
