Docker: Add negative usage test [Draft]

Signed-off-by: Chris Evich <cevich@redhat.com>
Oh woops, this test is dependent on version 0.8.1 so I rebased it.  What I should have done is just marked upstream as the ``docker_0.8.1`` branch.  Sorry about that, and thanks for pointing out the missing return, I'll take care of that in a different PR.
