It's possible that feature gates in TechPreviewNoUpgrade do not match the configured set of feature gates enabled in the downstream experimental manifests. This adds checks to ensure that they match.

The alternative would be to copy the manifest source into the operator-controller and catalogd bundles and then have cluster-olm-operator do the kustomize, but that would also require that cluster-olm-operator be able to update an overlay to create the proper selection of features, which could be difficult to manage.
