yatinkarel f93c9be1c1 Move to python3.9 as minimal python version
2023.2 release is targetting python3.9 as
minimal testing rutime[1]. openstack-tox-py38
job started to fail as libraries(like tooz) already
dropped py3.8 support.

This patch updates neutron py3 override job template
and setup.cfg to reflect the same.
