Restore bridge networkstatus checks in chutney
In chutney networks, there's a race condition when bridges try to publish their descriptor to the bridge authority:
- bridges try to publish their descriptors before bootstrapping
- but bridges can't publish their descriptors, because they don't have enough directory info to build a circuit to the bridge authority
Also, bridges do not retry publishing their descriptor immediately after they bootstrap.
- 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.
Also, the chutney workarounds seem to cause weird race conditions, which are time-consuming to diagnose and fix.
