cannot reference imagestream name and tag from StatefulSet image field, only DeploymentConfig in OCP 4.10.3

@dmage @benluddy @bparees I hope I am at the correct place here, found this online for [context](https://developers.redhat.com/blog/2019/09/20/using-red-hat-openshift-image-streams-with-kubernetes-deployments#): > Image streams are part of the OpenShift extension APIs. Other OpenShift extension resources, such as build configurations and deployment configurations, provide native support for image streams. OpenShift tooling, such as the oc command, offers easy-to-use commands to manage image stream resources, as well as other extension API resources. OpenShift adds its extension APIs using standard Kubernetes extension mechanisms, such as custom resource definitions (CRDs) and admission plugins. This feature allows OpenShift to support using image streams together with standard Kubernetes workload API resources, such as Deployments, StatefulSets, and Jobs. When I have an imagestream in the same namespace as a StatefulSet, I cannot use the image field and reference imagestream name and tag there. It does not get resolved. In contrast, when I reference the imagestream from a DeploymentConfig, or from a Pod, or from a Deployment, the image name and digest get resolved correctly, as it should be. Should this not have been fixed in the admission controller or something like that a long time ago, for all kinds of objects? See https://bugzilla.redhat.com/show_bug.cgi?id=2000216 and https://access.redhat.com/solutions/6455191 In any case, the expected result would be: image stream tags get resolved in created and edited StatefulSets.
