build: replace `distutils` with `setuptools`

This commit makes the build of Python packages use setuptools instead of the deprecated distutils in setup.py files. See PEP 632 for more information on the deprecation of distutils.

Note that using setuptools instead of distutils removes the following user warning messages when creating the bdist and sdist of the consumer and producer projects:

/usr/lib/python3.8/distutils/dist.py:274: UserWarning: Unknown distribution option: 'setup_requires'
  warnings.warn(msg)
/usr/lib/python3.8/distutils/dist.py:274: UserWarning: Unknown distribution option: 'install_requires'
  warnings.warn(msg)

See for example line 830 of https://gitlab.desy.de/asapo/asapo/-/jobs/453579#L830
