rac-4044 upstream updates appear to have broken FIT's run_tests.py

The following showed during recent (like 1/23/17ish) new checkouts of FIT where the mkenv was run on a ubuntu 16 box:

    *** Using config file: dellemc-test/config-mn/generated/fit-config-20170124-151936
    /emc/ohrenj/work/RackHD/test/.venv/fit/local/lib/python2.7/site-packages/nose/plugins/manager.py:395: RuntimeWarning: Unable to load plugin nosedep = nosedep:NoseDep: No module named extern.six RuntimeWarning)
    Usage: nosetests options

Problem tracked to version 34.0.x of setuptools. Other folk are hitting similar issues. Until this stabalizes, pin the setuptools version to 33.1.1 (last version before 34.0.0 came out).

Testing:
* before/after : python run_tests.py -stack vagrant -list worked on mac and u14
* before, same failed on u16
* after, same worked on u16
