Port a bunch of tests from python-k8sclient repository. There
is a script that starts a real instance of kubernetes and
the tests are executed against it.
Note, if you just have k8s accessible in your localhost:8080, the
tests still run. so you don't really need to run "py27-functional"
which runs the kube-init.sh
Also, 2 API calls fail currently, i've added a TODO so we can
dig into them and fix them
