add --enabled-ssl-passthrough by default in ingress-nginx
User report in: INC3605940
Without this setting the docs we have do not work: https://kubernetes.docs.cern.ch/docs/networking/services/#ingress-ssl-passthrough
so we need to:
- either add it by default, ideal if no side effects (seems like there are none, but double check)
- make it optional at cluster creation
The second option is an over complication that we need only if 1. adds an issue for other setups.
