Investigate address detection usage in Tor
Tor currently has a number of ways of detecting its own address when being used as relay. This includes:
- netinfo cell
- dirport connections to other relays
- configuration specification
It would be useful for the Arti WG to learn which of these methods are actively being used before we start implementing relay support in Arti.
A useful thing to do here is to enumerate the methods we have and extend MetricsPort to store information on where the relay learned its address for so we can make a sensible decision.
