six has no attribute 'add_metaclass'

[Avishay Traeger]

I have a patch failing in gate with traces containing the following:

2013-10-23 22:27:54.336 | File "/opt/stack/new/python-novaclient/novaclient/base.py", line 166, in <module>
2013-10-23 22:27:54.336 | @six.add_metaclass(abc.ABCMeta)
2013-10-23 22:27:54.337 | AttributeError: 'module' object has no attribute 'add_metaclass'

For full logs, see the failing patch:

It looks like this was caused by this recent commit:

This should be marked as critical and fixed in Havana but doesn't apply to trunk

Thanks for taking care of this!
