Task API change: use tuple instead of set for input/output names

When using required_input_names, optional_input_names etc. from Task we often need deterministic sorting: https://gitlab.esrf.fr/workflow/ewoks/ewokscore/-/merge_requests/277 (task discovery) and https://gitlab.esrf.fr/workflow/ewoks/ewokscore/-/merge_requests/320 (ewoks show).

I proposed to break the API and use tuples instead of sets.
