Following the step described in the enhancement, we should do the following:

• Move existing code from openstack-cinder-csi-driver-operator into a legacy directory in the csi-operator repository,
• Add a Dockerfile for building the operator image from the new location,
• Update openshift/release to build the image from new location,
• Change ocp-build-data repository to ship image from new location, and
• Coordinate merges in ocp-build-data and release repository

Once this is done, we can work towards rewriting the operator to take advantage of the new generator tooling used for existing migrated operators.
