This patch updates hacking and bandit versions to match what neutron
and others are doing. It also fixes and ignores some new pep8 errors
that crop up due to the version bump. Finally the doc requirements are
moved to doc/requirements.txt to match what other projects do, even
though this project does not build docs today.
