    Support of Python3.10

    This change includes required changes to make tests work in Python3.10.
    It also enables tox running as part of stage-test, which was not included before.
    For the moment, only flake8 and black envs will be checked. Some pylint
    errors have been fixed, but a few remain unsolved. That's why pylint is
    run, but its result is ignored.
