Feature Overview

Enable ClusterCurator to automatically resolve and inject image digests into the ClusterVersion resource when upgrading to OpenShift non-recommended versions using the annotation upgrade-allow-not-recommended-versions: 'true' , to support disconnected environments that require digests (due to ImageDigestMirrorSet).

Goals

Ensure that ClusterCurator sets the ClusterVersion.spec.desiredUpdate.image using a digest rather than a tag, by fetching it from either status.conditionalUpdates or status.availableUpdates. This prevents ImagePullBackOff issues in disconnected clusters and removes the need for manual scripting or patching as part of the upgrade flow.
