Comment 4 for bug 1346387

I'm not sure exactly when it was fixed but now H306 is certainly enabled in Trove. To verify I just switched the order of a couple of imports and ran tox

pep8 runtests: commands[0] | flake8
./trove/common/cfg.py:21:1: H306 imports not in alphabetical order (oslo_log.log, oslo_config.cfg)
from oslo_config import cfg
