Backport 8594d1c from #18250


What this PR does / why we need it:

#13940 introduced a change for memberlist to pick address from the interfaces defined in common instance_interface_names (previously it iterated over all available interfaces), but the method used only resolves v4 addresses.

This breaks memberlist for anyone using v6 only interfaces. This PR updates memberlist to look-up t.Cfg.Common.Ring.EnableIPv6 flag to enable the resolution of v6 addresses.

Note: Individual components are allowed to specify their own list of interfaces using <component_name>.ring.instance-interface-names but memberlist does not consider the component specific setting yet. This should be fixed in the long term.

  • Changes that require user attention or interaction to upgrade are documented in docs/sources/setup/upgrade/_index.md
  • If the change is deprecating or removing a configuration option, update the deprecated-config.yaml and deleted-config.yaml files respectively in the tools/deprecated-config-checker directory. Example PR
