six==1.5.2 conflicts with model_mommy-1.2's six==1.0.3

[Vincent Ladeuil]

This was revealed by using run-tests and is masked by ./tarmac running setup.py develop ; setup.py test for one component after the other.

Recipe:

# source your cloud credentials (otherwise the tests are skipped)

$ rm -fr .venv ; virtualenv .venv
$ ./tarmac.sh .venv

I ran into the issue in a branch I've been working on where I diagnosed that we have a conflict on six:

- we want to use 1.5.2 (especially for keystoneclient),
- we use model_mommy-1.2 which requires six==1.3.0
