Cluster upgrade is stuck as Upgrade of ClusterOperator fail with network Progressing	4.18.18	Deployment "/openshift-multus/whereabouts-controller" is not available.

The pod in openshift-multus namespace is in CreateContainerError state: 
pod/whereabouts-controller-6cdb576698-js5rg        0/1     
CreateContainerError   0          1h
     waiting:

From the events I can see:

is missing the "node-slice-controller" executable here.

   4.18.19 

    Try upgrading to 4.18.19

    1. Create 4.18.18 cluster
    2. Enable additional networks
 
  additionalNetworks:
  - name: whereabouts-shim
    namespace: default
    rawCNIConfig: |-
      {
       "name": "whereabouts-shim",
       "cniVersion": "0.3.1",
       "type": "bridge",
       "ipam": {
         "type": "whereabouts"
       }
      }
    type: Raw
 
    3. Try updating to 4.18.19
    4. When upgrading to 4.18.19 additional pods are created - the whereabouts-controller is the one that does not work throwing CreateContainerError.
    

    To workaround the upgrade issue it is needed to remove the additionalNetworks which will remove the DaemonSet and the upgrade can continue.
