By default, pep8.py ignores E226 and E24. By changing
tox.ini to not have an ignore clause, it started using
the default. Since we were explicitely ignoring things
until recently, E226 and E24 where being checked. This
patch adds an ignore clause to tox.ini and fixes some
E226 errors to match our pep8 checks to other projects
in openstack.
