Periodic job openstack-tox-py39-with-oslo-master is broken

[Slawek Kaplonski]

This periodic job is failing constantly starting from 21.07.2022. Errors are the same every day:

Surprise: oslo.db master is enough for me to reproduce the failures, perhaps some of these:
$ git log --oneline --no-merges 12.0.0..HEAD
e7642fd tox: Silence output
4c451b7 trivial: Don't emit warnings for our own deprecations
2c7c0ca tests: Enable SAWarning warnings
a530cbf Remove the 'Session.autocommit' parameter
4314279 Add missing 'connect' wrapper

In my local env "a530cbf Remove the 'Session.autocommit' parameter" seems to be guilty

    ``Session.autocommit`` parameter is removed

    Since [1] (in oslo.db>9.1.0), the ``Session.autocommit`` member
    is removed and should not be considered. This patch removes this
    dependency while keeping backwards compatibility. This code will
    be removed in future releases.

    Due to the neutron-lib dependency, this patch bumps the needed
    library version to 3.1.0.
