Some people put their local relay addresses (local host) and onion addresses in their relay list. Onion addresses will fail if the client does not support tor and local host addresses are obviously not accessible. I think we should not select and attempt to connect to addresses that are known to be of no use.

Context: I'm observing relay statuses with `Monitor` and noticed many failed connections to localhosts and onions. I'm on v0.44.0
