Update requirements to OpenStack's recommendations

This synchronizes requirements.txt, test-requirements.txt and
setup.py with the current state of the openstack/requirements
global-requirements.txt list. Also adds flake8 exclusions to tox.ini
for new hacking rules with which git-review does not yet comply.
