Refactor gr-rest-api-interface to use rest-client-behavior

Significant unnecessary code duplication existed between the two
files, most importantly an enum that existed and was mirrored in both
places. This change removes all duplicate code from the interface,
preferring the publicly accessible nature of the behavior, and changes
private function calls within the interface accordingly.
