Ensure openshift-dns-operator is running on hosted control planes

Overview 

Customers do not pay Red Hat more to run HyperShift control planes and supporting infrastructure than Standalone control planes and supporting infrastructure.

Assumption

• A customer will be able to associate a cluster as “Infrastructure only”
• E.g. one option: management cluster has role=master, and role=infra nodes only, control planes are packed on role=infra nodes
• OR the entire cluster is labeled infrastructure, and node roles are ignored.
• Anything that runs on a master node by default in Standalone that is present in HyperShift MUST be hosted and not run on a customer worker node.

DoD 

• openshift-dns-operator controller is running on the CP. 

• A CI hypershift presubmit runs on the operator repo.
