allow subject access review to non-existent namespace
A localsubjectaccessreview is a special kind of resource which can be created even when the namespace doesn't exist. Since permissions can be granted at different scopes, you can reasonably check if someone *could* do something at a lower scope that isn't there yet. In addition, the permission to do an access check is separate from the permission to list all namespaces, so we're leaking information.
