Use flake8/hacking, as is standard in other OpenStack projects, but
disable new checks -- they will be enabled in later patches.

http://flake8.readthedocs.org/en/2.0/warnings.html, and hacking enforces
the OpenStack Style guidelines, including things like one import per
line and alphabetical imports in order to make merging easier.

Per http://wiki.openstack.org/ProjectTestingInterface we enable all
of the commands except build_sphinx because we do not have any sphinx
documentation as of yet. Includes babel support though there are no
properly internationalized strings just yet.
