[api] Creation of an object does not return its final full name
I just realised that, when we create a new object, the API only returns an empty message with a 200 status code. It is not possible to be assertive about the full name the object will take on the other side. That would imply, at least, in 2 API calls (one for
check_name before the post), and hope for the best on the naming, including bumped version numbers accounting.
In summary, all create APIs, new versions, forks, etc should return the final object created full name + at least the view URL of the object.
