The MCO should allow users to skip image registry change disruption

      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
