+++ This bug was initially created as a clone of Bug #1755784 +++

Description of problem:

Nodes become NotReady due to Missing CNI default network with OVN plugin on Azure.
When new nodes are added to cluster through auto-scaling, nodes stay in NotReady state with below messages.

runtime network not ready: NetworkReady=false reason:NetworkPluginNotReady message:Network plugin returns error: Missing CNI default network

Version-Release number of selected component (if applicable):

$ oc get clusterversion

How reproducible:



Steps to Reproduce:
1. Setup IPI on Azure with networkType: "OVNKubernetes"
2. Try to add nodes through auto or manually scaling.
