For the effort to deliver the UpdateStatus API in 4.19 we made DevPreview OCP deploy the Update Status Controller skeleton via payload manifests: new namespace, service account, rbac and deployment. We are not going to ship any meaningful UpdateStatus API implementation in 4.19, so we should remove all these manifests so that no useless ballast is deployed on 4.19 clusters after GA, even in DevPreview. We also have CI jobs / tests that exercise USC deployment in DevPreview; these need to be removed / disabled as well.
