- Update to 4.0.1:
* Fixed an issue around the unittest runner unexpectedly not running the
requested tests (or executing them in an unexpected order) causing odd
failures that were difficult to debug.
* Fixed the output handling of stestr run and stestr load so that any
segfaults or unexpected failures in a test worker are now properly
reported in the subunit-trace output.
* Drops support for the 'sql' repository type and also the flags and
Python API flags for selecting the repository type.
* Remove support for running with Python 3.5.
* Official support for Python 3.10.
* Fixed the execution order of the stestr run --load-list option so that
tests are executed in the order specified in the list.
- Add patch remove-future-requirement.patch, drop use of the future module.
- Switch to pyproject and autosetup macros.
