----------------------------------+---------------------------
 In chutney networks, there's a race condition when bridges try to publish
 their descriptor to the bridge authority:
 * bridges have AssumeReachable set
 * 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.

 Once we make bridges do reachability checks in chutney, they will wait to
 bootstrap, do reachability checks, then try to publish their descriptors.

 So we can enable the bridge networkstatus checks again.
