Change log level for get_all_addresses and get_any_address (#2850)

Logging an exception for every missed address resolution has these issues:
* Even when there are no faults, users stumble on these and we receive spurious fault reports over slack. It makes for a bad first impression
* These non-critical errors act as a diversion from real faults for users attempting to debug on their own.
