Replace Kind with GroupVersionKind
Kind is not unique to track resources in Kubernetes GroupVersionKind is unique. We are just using that to track our data. It is abstracted behind a couple of new types for templates and resources. This change makes a lot of the old kind based operations redundant and simplified.
