Is your feature request related to a problem? Please describe. Deployment works great in a dual-stacked set-up, however, there is no way for me to set the ipFamilyPolicy to "preferDualStack"

Describe the solution you'd like Being able to pass this variable would be great, but to be on the safe side, I'd keep it set to singlestack (to keep working as currently expected).

Describe alternatives you've considered The alternative is me manually adjusting the service to include this.

Just thinking out loud here... should I also include the ipFamilies option to be complete? This way a singlestack ipv6 could be created as well
