Merge remote-tracking branch 'tor-gitlab/mr/107' into maint-0.4.4

changes/bug40083

+  o Minor bugfixes (relay, self-testing):
+    - When starting up as a relay, if we haven't been able to verify that
+      we're reachable, only launch reachability tests at most once a minute.
+      Previously, we had been launching tests up to once a second, which
+      was needlessly noisy. Fixes bug 40083; bugfix on 0.2.8.1-alpha.
