Currently, new OCI base images for RHCOS are not automatically built and pushed into OpenShift, unlike their ostree-native counterparts.

To facilitate this, we can make use of the pre-existing Jenkins jobs for RHCOS which handle the ostree-native versions, amongst other things. There's already some prior art in the form of a merged PR (https://github.com/coreos/fedora-coreos-pipeline/pull/457) to the FCOS pipeline repository. An equivalent PR should be made to the RHCOS pipeline repository (https://gitlab.cee.redhat.com/coreos/redhat-coreos) as well.

Done When:

• The destination container registry is determined.
• What access controls the above container registry should have, including push secrets for us to use. (Stretch: Do we need to consider Red Hat subscriptions for registry access?)
• The RHCOS pipeline is modified to enable automated container pushes to the above container registry.
