Allow user of documented api to call the method itself

[liorsion]

The idea is that for each documented method, the client will be able to test it in the same sport using required parameters.

Please see beginning of work here, I can do pull request so we can work on it together on a different branch, or just send me samples of your api so I can start working on it.

This seems like a very nice feature we were thing about previously. For samples, theforeman is a good project to try that on: e.g. https://github.com/theforeman/foreman/blob/develop/app/controllers/api/v1/operatingsystems_controller.rb
