This introduces a new stream the syncAPI produces to once it processed a `OutputRoomEvent` and the appservices consumes. This is to work around a race condition where appservices receive an event before the syncAPI has handled it, this can result in e.g. calls to `/joined_members` returning a wrong membership list.
