tests: cover port with existing sorting/pagination api tests

This is based on existing network api tests for the features that were
implemented in an extensible way.

Existing list_kwargs is decoupled from the base test class because they
are network test specific. Also removed generic handling for
create_method because each resource has its own signature for creation
methods, so it's easier to implement it per resource than trying to come
up with a generic solution.
