feat(cmd): add local-config annotation on create

this adds a DefaultMetadata object in konfig that can be used
when creating a new kustomization yaml that conforms with the
best practice recommendations in the kustomize docs.

> The `Kustomization` config in a `kustomization.yaml`
> **SHOULD** contain this annotation so that tools know it is not intended to be sent to
> the Kubernetes api server.
