Enable pep8 on the integration directory

[Amrith Kumar]

Currently trove/integration is disabled for pep8. This should be fixed but it is a non-trivial effort.

What you have to do:

1. Wait till https://review.openstack.org/398935 Enable hacking extensions framework merges
2. Update tox.ini and in the flake8 section, change the line that excludes 'integration'. See below.

[flake8]
show-source = True
# H301 is ignored on purpose.
# The rest of the ignores are TODOs.
ignore = F821,H301,H404,H405,H501
enable-extensions = H203,H106
builtins = _
exclude=.venv,.tox,.git,dist,doc,*egg,tools,etc,build,*.po,*.pot,integration
filename=*.py,trove-* ^^^^^^^^^^^

3. Once you delete 'integration', re-run tox -e pep8, you will be rewarded with a considerable number of errors. Fix ALL of them till you can get pep8 to pass.
4. Then verify that py27 and py34 also pass.
5. Then submit a change with your new tox.ini and all the changes you made

Good luck

    Enable hacking extensions framework

    <long rant deleted>

    This change enables the hacking extensions ability in trove. That
    includes bumping the version of hacking that we use, and also adding
    the enable-extensions like in the [flake8] section. I've enabled two
    of the hacking extensions here.

    There are some limitations to the hacking rules that I've enabled so
    I'm also going to enter two bugs that others can fix (if they so
    desire).
