As discussed at the Epoxy PTG meeting, run an automated upgrade tool to make code python 3.9+ compliant. This patch is for code (non-tests). Result of running: $ pyupgrade --py39-plus $(git ls-files | grep ".py$") Fixed PEP8 errors introduced by pyupgrade by running: $ autopep8 --select=E127,E128,E501 --max-line-length 79 -r \ --in-place neutron Also did manual updates as necessary to fix other errors and warnings after above commands. Inspired by Octavia and Nova [0]. [0] https://review.opendev.org/c/openstack/nova/+/896986 Change-Id: Ife79df75dd2c9c42d4de36edef1d29b98f5d85da
