When removing the "mock" module from python-octaviaclient, it was
clear that python-octaviaclient did not follow the same coding
style guides as the main octavia project.
This patch corrects that by updating the code style checks in
python-octaviaclient to those of the octavia repository and
corrects any style issues found by the new tests.
