Description of problem:
Install upi-on-vsphere with nightly build 4.7.0-0.nightly-2020-12-20-031835. After installation is completed, then try to update machine-config.
For example, apply below new "ImageContentSourcePolicy":

apiVersion: operator.openshift.io/v1alpha1
kind: ImageContentSourcePolicy
metadata:
  name: brew-registry
spec:
  repositoryDigestMirrors:
  - mirrors:

    - brew.registry.redhat.io
    source: registry.stage.redhat.io
  - mirrors:
    - brew.registry.redhat.io
    source: registry-proxy.engineering.redhat.com

Then waiting for machine-config update, but mco is degraded with error:
# ./oc get co | grep machine-config
machine-config                             4.7.0-0.nightly-2020-12-20-031835   False       False         True       15m

    worker: 'pool is degraded because nodes fail with "1 nodes are reporting degraded status on sync": "Node compute-1 is reporting: \"error enabling unit: Failed to enable unit: Unit file nodeip-configuration.service does not exist.\\n\""'

Then checked on node, it is indeed not find file nodeip-configuration.service. And this service should only be present on ipi-on-vsphere cluster.
