Description of problem: 

Machine-api-controller does not reconcile automatically after a vCenter password change.

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

Openshift Container Platform 4.17.31 and 4.19.0

How reproducible:

All the time

Steps to Reproduce:

Followed Red Hat Openshift Documentation Section for vCenter: "Rotating cloud provider credentials manually":

1. Start with a fresh cluster.
2. Change vCenter Password.
3. Change `vsphere-creds` secret to the new password.
4. (Optional just to follow the documentation) Force a KCM redeploy with:

   oc patch kubecontrollermanager cluster -p='{"spec": {"forceRedeploymentReason": "recovery-'"$( date )"'"}}' --type=merge

Actual results: 

The machine-controller container logs shows a `401 Unauthorized` error that only stops after a manual delete of the pod:

$ oc logs -n openshift-machine-api -f machine-api-controllers-78586bb75-b4zpp -c machine-controller 
[...]
E0701 08:25:42.021995       1 actuator.go:63] "master-node" error: master-node: reconciler failed to Update machine: failed to reconcile tags: POST https://VCENTER-URL/rest/com/vmware/cis/session: 401 Unauthorized

Expected results: 

The machine-api operator should restart the pod to update the new credentials and evade possible vCenter account lockups due to security policies.

Workaround:

An identified workaround is to manually delete the pod so it restarts with the new credentials:

oc delete pod -n openshift-machine-api -l k8s-app=controller
