should the 2nd arg be an FeedbackAdaptor?

As agreed with Stefan, CongestionController is now the
TransportFeedbackObserver. For now, I am passing it as a
TransportFeedbackObserver, but a later CL will (probably) change that to being
passed as a full-fledged CongestionController (rather than exposing the subset
of capabilities embodied in TransportFeedbackObserver), thereby allowing some
further cleanup.
