    Description

      This is a clone of issue OCPBUGS-11142. The following is the description of the original issue:

      Description of problem:

      With the recent update in the logic for considering a CPMS replica Ready only when both the backing Machine is running and the backing Node is Ready: https://github.com/openshift/cluster-control-plane-machine-set-operator/pull/171, we now need to watch nodes at all times to detect nodes transitioning in readiness.

      The majority of occurrences of this issue have been fixed with: https://github.com/openshift/cluster-control-plane-machine-set-operator/pull/177 (https://issues.redhat.com//browse/OCPBUGS-10032) but we also need to watch the control plane nodes at steady state (when they are already Ready), to notice if they go UnReady at any point, as relying on control plane machine events is not enough (they might be Running, while the Node has transitioned to NotReady).

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

      4.13, 4.14
