kube: standardize on a `local ns` convention
A convention is introduced to specify the kube.Namespace object in a deployment as a `local ns` instead of an `ns:` or a `namespace:` for these reasons:
- non-cluster admins cannot create new namespaces, and we've been moving in the direction of specifying objects that require cluster admin permissions to apply (policies, role bindings) in //cluster/kube/k0 instead of in the app jsonnet
- namespace admins CAN delete the namespace, making `kubecfg delete` unexpectedly dangerous (especially if a namespace contains more than just the contents of the file being applied - common with personal namespaces)
- `.Contain()` is a common operation, and it shows up in lines that are pretty long, so `ns.Contain()` is preferable to `app.ns.Contain()` or `service.namespace.Contain()`
