Apiv2

I created a new branch to be able to use the v2 of the Foreman API

Unfortunately there is a parameter in the api (in method import_puppetclasses for the objects smart_proxies and environments) that is called 'except' and it triggers an exception when trying to generate the functions in python since it is a reserved word.

As a workaround I filtered it out but I'm sure that you'd fine a much better solution for that.
