Windows Nodes are occasionally failing to reach the ready state due to CNI issues
    

Able to reproduce in AWS
    

    1. SSH onto the Windows Node
    2. In powershell run: rm /k/cni/config/cni.conf; New-Item /k/cni/config/cni.conf -type file
    3. Wait for node to go to not ready
    

Windows Node goes to NotReady, and does not go back to Ready, the following can be seen in the logs:

                        "type": "Ready"
                    }
    

Windows Node goes to NotReady for less than 5 minutes, before returning to Ready
    

Has only been observed after the merge of https://github.com/openshift/windows-machine-config-operator/pull/1979
Manual workaround:  SSH onto the Windows VM, delete /k/cni/config/cni.conf and wait a few minutes
