Fix Ruby and Python REST API examples

The previous examples where wrong, since they used a POST request.
I used the requests library for Python, since that is what most people
would want to use.
I removed the http.verify_mode in the Ruby example since I don't think
it is good practice to tell people to not verify HTTPS requests
