Rewrites Marvelite::API::Client for auto-discovery of available methods

Marvelite::API::Client, now only requires to know which routes its

This is a first draft in removing the dependency to manually declare
available methods for the client. Thanks to [Ismael
Marin](https://github.com/igmarin) for the idea and inspiration.
