    Description

      This is a clone of issue OCPBUGS-27508. The following is the description of the original issue:

      Description of problem:

      The MCO logic today allows users to not reboot when changing the
      registries.conf file (through ICSP/IDMS/ITMS objects), but the MCO will
      sometimes drain the node if the change is deemed "unsafe" (deleting a
      mirror, for example).
      
      This behaviour is very disruptive for some customers who with to make
      all image registries changes non-disruptive. We will address this long term with admin defined policies via the API properly, but we would like to have a backportable solution (as a support exception) for users to do so
