removed non implemented API JSON files

Solve #32
The Swagger UI present available API base on JSON definition files.
Once one try to use them, he gets a 404 response.
This patch removed two such non implemented JSON files.
Once and if the API are implemented on the server, we should bring the JSON files back.
