This PR suggest that it's possible to manage also azure private dns zones with external-dns-operator (edo).

When I run this command with the latest edo can I also see some private dns output.

In the official doc is this not documented. Is the azure private DNS "just" not supported but possible or not available in the operator?

What I understand in the CRD is the Azure private DNS not listed, right?

@git001: there is a documentation gap for the support of the private Azure zones indeed. From the API point of view, it's still the same provider: Azure. However the private zones set in .spec.zones will be configured with azure-private-dns provider flag as required by the upstream.
