Make chutney bridge authorities publish bridges in their networkstatus-bridges
Chutney bridge authorities don't have any bridges in their networkstatus-bridges. That's a problem, because we want to check networkstatus-bridges for the reachability checks in #33232 (moved).
Once bridges upload their descriptors, we can make chutney check the bridge authority's networkstatus-bridges for bridge nicknames (this ticket).
- the next tor 0.4.4-alpha version, or
- an environmental variable that enables these tests.
We don't have to do these fixes, because it should be enough to test relay reachability. But we would risk breaking bridge reachability tests, and not knowing about it until after a release.
