Great stuff, really happy to see Python 3 support.

If I can help somehow, let me know.

I think the import needs to be changed to this, as openstack is under the
os_collect_config package.

    from os_collect_config.openstack.common import log

Alternatively, `from .openstack.common import log` should work but that 
is less favorable.

I don't have a change, but FWIW I just tried the tests locally on py33 
and they passed fine. \o/
