Purge an Accidentally Pushed Image From a Container Registry

Sometimes an image needs to be removed from a registry - because it was pushed by mistake, contains sensitive data, or simply should no longer be available. Practice purging a container image properly: remove the tag, trace it to the manifest and blobs behind it, and make sure the image can no longer be pulled - even by digest.
