A cluster-scoped controller cannot update or delete namespaced resources

[silverlyra]

I'm writing a cluster-scoped CompositeController that sometimes needs to create Pods, which are of course namespaced.

I don't think the support for this in Metacontroller is working. When my controller omits a Pod it had created from the children it returns, metacontroller can't delete it, and logs an error on every reconcile:

can't reconcile children for <the custom resource>: can't delete Pod <ns>/<name>: the server could not find the requested resource

I'm guessing that ManageChildren's deleteChildren helper chokes on the namespace/name keys Metacontroller generates for namespace-scoped children with a cluster-scoped parent:

for name, obj := range observed {
	if desired == nil || desired[name] == nil {
		err := client.Namespace(obj.GetNamespace()).Delete(name, …)
	}
}

If name here is really "namespace/name", that's not going to work. It looks like updateChildren is affected as well.
