--------------------------------+--------------------------------
 In #33880, we adjusted the limits MIN_RELAY_CONNECTIONS_TO_WARN, and the
 default number of connections allowed per relay.

 In #33048, we will allow relays to extend via IPv6 as well as IPv4. So we
 should make these changes:
 * warn if any relay has more than 4 connections (that is, more than 2
 sides multiplied by 2 IP addresses, if there is disagreement over
 canonical connections).
 * ignore 2 connections per relay.

 Clients should only extend between two relays that support the Relay=3
 protocol version. So we shouldn't need to backport this change.
