In a setup where we have a waypoint and a service configured to use waypoint for ingress traffic (Istio's ingress-use-waypoint), the waypoint plugin configures the gateway with the service VIPs.

However, if the VIPs is a combination of IPv4 and IPv6 there is control on the IP family preferences.
I.e. setting KGW_DNS_LOOKUP_FAMILY has no affect.

There are some scenarios where specific family is preferred (e.g. IPv4) and the traffic will still be load balanced to the other family.

We wish to be able to control this or have it at least set to V4_PREFERRED (the default for the KGW_DNS_LOOKUP_FAMILY).
