Use apiextension v1

- upgrade from apiextension v1beta1 to v1
 - generate yaml manifest for crd intead of applying it at runtime
  - users will have to apply the manifest with kubectl
 - kg and kgctl log an error if the crd is not present
 - now validation should actually work

+# github.com/gobuffalo/flect Stands on the Shoulders of Giants
+
+github.com/gobuffalo/flect does not try to reinvent the wheel! Instead, it uses the already great wheels developed by the Go community and puts them all together in the best way possible. Without these giants, this project would not be possible. Please make sure to check them out and thank them for all of their hard work.

+Thank you to the following **GIANTS**:
