Use keyset pagination instead of offset pagination #961

Description of the problem, including code/CLI snippet

This package currently does pagination through page and per_page arguments. This can be problematic because some results could be skipped (for example, if some older result gets deleted in meantime).

Expected Behavior

Recently, GitLab (and already available on gitlab.com) supports also id_after and id_before. So this package could support iterating over many results by: ordering by ID and then using id_after to get the next set of results.
