update client-gen to use the term "internalversion" rather than "unversioned"; leave internal one unqualified; cleanup client-gen
This dir can not be named "testdata" because of the way ugorji gnerates code. Specifically, it emits a .go file and then calls `go run` on it. Because "testdata" is a special name to Go, it decides NOT to find the vendor dir, and therefore fails to compile. Just name it something else.
