Fix configmap name case error

[hangyan]

For somehow, all the Name field of configmaps(object ref) does not serialize correctly, strangely only k8s templates was affects. Seems like the cause is

vendor/k8s.io/kubernetes/pkg/api/types.go
// LocalObjectReference contains enough information to let you locate the referenced object inside the same namespace.
type LocalObjectReference struct {
	//TODO: Add other useful fields.  apiVersion, kind, uid?
	Name string
}

For now i will update the vendor code and use vendor-update to keep it sync.
