config: Add IPv4 Address config debug logging

Browse Source 
Per ticket #32888 this should address logging "the Address torrc
option", "and whether it is an IP address, or a DNS name"; or the
detected "local hostname", "and whether it is an IP address, or a DNS
name". Some of these details already seem to be logged, so just add
what's missing.
