Generate BMH CRD with annotations needed for OpenShift

[sadasu]

• Add a new kustomization file that adds the OpenShift annotations
• Only on the OpenShift platform, use this file to generate the BMH CRD
• Copy this generated CRD to the /manifests directory so that the CVO can install it

This fix is being added so that the BMH CRD does not have to be manually kept in sync with the BMO CRD.

@andfasano - If you are Ok with the generic approach, this PR can be used just for adding ocp_kustomization.yaml. The Dockerfile.ocp changes will then be able to find this file in a later PR for the COPY command to be successful.

if this approach seems reasonable, I will split it into 2 PRs where the ocp_kustomization.yaml goes in first.
