neutron_fwaas/tests/unit/db/firewall/test_firewall_db.py

    py34 support for fwaas

    Add py34 support to the modules listed below:
    test_firewall_db
    test_firewall
    test_vyatta_utils
    test_vyatta_fwaas
    test_csr_firewall_svc_helper
    test_fwaas_plugin

    Most work is done by introducing python-six
    to bridge the gap between py27 and py34.

    At this stage, py34 support is finished for fwaas.
