This branch logs the names of Tor guards and bridges that we directly connect to, to improve our ability to debug connection issues from user feedback. I'm adding this because I received a log from a user in Belarus where it was clear that bridge connections were failing, but not clear which bridges were being tried each time.
The orName that gets logged is a 40 hex character fingerprint, followed by the relay's name (e.g. moria1) if it has one.
