Like Delete, which can now run over multiple types:
kubectl delete pods,services -l name=foo
Get should be able to span items for label selection
kubectl get pods,services -l name=foo
Add a Visitor pattern on top of ResourcesFromArgs
Allows ResourcesFromArgs to return an opaque list of items and have client
commands react to them.
Change request.go to return apiserver errors for arbitrary status codes to
better respond to generic actions that don't make sense (kubectl delete operations foo)
* Ensure kubectl uses abstractions from other parts of Kube
* Begin adding abstractions that allow arbitrary objects
* Refactor "update" to more closely match allowed behavior
