Subject: [PATCH] Register opts if we're going to check conf.transport_url in
parse()
In TransportURL.parse(), a classmethod, we expect conf.transport_url
to be accessible if a url is not passed in. However, since the
_transport_opts are not registered yet, that will fail, which is
a pretty easy case to hit if we're constructing our TransportURL
for the first time on startup.
This registers the opts if we're likely to hit it.
