Description of problem:

(copy and pasted from https://issues.redhat.com/browse/NE-226)


on Azure currently we use DNSZone resource with type `Private` to store the DNS records private to the cluster.

There are certain shortcomings with this resource when using type `Private`

1) This has been deprecated by Azure for  Private DNS Zones preview

2) This does not allow attaching itself to pre-existing Virtual Networks

The new resource Private DNS Zone solves all the shortcoming of the previous generation and is required for Installing OpenShift in pre-exisiting VNets in Azure.

The ingress-operator will need to support the `.spec.privateZone.id` to be either of the 2 resources.

The long-term goal is to migrate 4.2 clusters to new resource, but for 4.3 we are only required to support the install time choice, i.e. the change of this ID in-cluster as day-2 does not need to be supported.

Migration epic is here https://docs.google.com/document/d/1j5pJbmAQ4-FVR2H0S5OWAaX7rImBcPP0RC-uLlM1WrE/edit#heading=h.9khfep37qdjo
