Add lower-level methods for Gitlab()

Multiple goals:
* Support making direct queries to the Gitlab server, without objects
  and managers.
* Progressively remove the need to know about managers and objects in
  the Gitlab class; the Gitlab should only be an HTTP proxy to the
  gitlab server.
* With this the objects gain control on how they should do requests.
  The complexities of dealing with object specifics will be moved in the
  object classes where they belong.
