      * Previously, machine config pools (MCP) that had a higher `maxUnavailable` value than the cluster has unavailable nodes, cordoned nodes could be erroneously selected as an update candidate. This fix adds a node readiness check in the node controller so that cordoned nodes are queued for an update. (link:https://issues.redhat.com/browse/OCPBUGS-33397[*OCPBUGS-33397*])

      Description of problem:

      Node has been cordoned manually.After several days, machine-config-controller uncordoned the same node after rendering a new machine-config.

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

          4.13

      Actual results:

      The mco rolled out and the node was uncordoned by the mco

      Expected results:

       MCO treat unscedhulable node as not ready for performing update. Also, it may halt update on other nodesĀ  in the pool based on what maxUnavailable is set for that pool
