Mildly wound the interlopers

This commit removes all the references to nose in the tempest tree.
Moving forward trying to support nose which doesn't support some of the
features we rely on in tempest is increasingly difficult. Please refer
to this thread:

http://lists.openstack.org/pipermail/openstack-dev/2014-January/024673.html

for a more detailed explanation and the discussion regarding this.

-# there is a mis-match between nose and testtools for older pythons.

-# exception, depending on what it can find. Python <2.7 doesn't have
-# unittest.case.SkipTest; so if unittest2 is not installed it falls

-#
-# The current nose skip plugin will decide to raise either
-# unittest.case.SkipTest or its own internal exception; it does not
-# look for unittest2 or the internal unittest exception.  Thus we must
-# monkey-patch testtools.TestCase.skipException to be the exception
-# the nose skip plugin expects.
-#
-# However, with the switch to testr nose may not be available, so we
-# require you to opt-in to this fix with an environment variable.
-#
-# This is temporary until upstream nose starts looking for unittest2
-# as testtools does; we can then remove this and ensure unittest2 is
-# available for older pythons; then nose and testtools will agree
-# unittest2.case.SkipTest is the one-true skip test exception.
