"A" records created for both, Endpoint and LB IP in Azure Private DNS #4819

What happened:

I have a Service with the following manifest:

apiVersion: v1
kind: Service
metadata:
  annotations:
    external-dns.alpha.kubernetes.io/hostname: svc1.prod.domain.internal
    service.beta.kubernetes.io/azure-load-balancer-internal: "true"
status:
  loadBalancer:
    ingress:
    - ip: 10.2.2.7
[...]

Now ExternalDNS creates two A records for "svc1.prod.domain.internal", one for the IP address "10.2.2.7" (which is expected) and another one for the IP address "10.244.0.46" which is the IP address of the underlying Endpoint/Pod.

What you expected to happen:

A single A record pointing to "10.2.2.7" is created for "svc1.prod.domain.internal". No A record is created for the Endpoint IP.

How to reproduce it (as minimally and precisely as possible):

see above.
