Take pagination into account

[Viicos]

In the list method of the client, the return type is supposed to be List[Object] even though the response can be paginated (and thus being an object of the following form: {"count": 1, "next": ..., "previous": ..., "results": [...]}.

Depending on whether you want pagination to be handled by the client or not, we can either:

• change the return type to Union[Object, List[Object]]| and let the user handle pagination
• make something more advanced to handle paginated responses in the client.
