What happened: DNS Servers remain unchanged. Output of azure-vnet.log:

What you expected to happen: DNS Servers should have changed to 8.8.8.8.

How to reproduce it (as minimally and precisely as possible): Create a pod on a Windows node using the yaml below and check the output of azure-vnet.log to see if the DNS Servers have changed to 8.8.8.8.

apiVersion: v1
kind: Pod
metadata:
  namespace: default
  name: dns-utils
spec:
  containers:
    - name: util
      image: claudiubelu/dnsutils:1.1
      command: ["powershell", "sleep", "1000"]
  dnsPolicy: "None"
  dnsConfig:
    nameservers:
      - 8.8.8.8
