Revert "cleanup setup.py config"

This reverts commit 6c976e61a9.

Reason for revert:
Removal of setup.py caused problems with installation in tripleo-quickstart:

2022-03-31 16:20:19.128604 | primary | ERROR: openstack-ansible-os_tempest from file:///home/zuul/src/opendev.org//openstack/openstack-ansible-os_tempest/#egg=openstack-ansible-os_tempest (from -r quickstart-extras-requirements.txt (line 5)) does not appear to be a Python project: neither 'setup.py' nor 'pyproject.toml' found.

Disable setuptools auto discovery

Jobs are broken due to a release of setuptools 61.0 introducing
non-backwards compatible breaking changes [1]

Setting py_modules to an empty string here will disable autodiscovery
and should permit jobs to run as before.
