cmd/k8s-operator: Allow specifying cluster ips for nameservers (#16477)

Browse Source 
This commit modifies the kubernetes operator's `DNSConfig` resource
with the addition of a new field at `nameserver.service.clusterIP`.

This field allows users to specify a static in-cluster IP address of
the nameserver when deployed.

Fixes #14305
