* Update to work with k8s 2.0
This makes the necessary changes to get the collection working with
kubernetes.core 2.0. The biggest changes here will be switching from the
openshift client to the kubernetes client, and dropping Python 2
support.
* Install kubernetes not openshift

* Clean up CI build
There were a few problems with the existing build process, such as, the
python version not being passed during sanity tests and versions being
hard coded elsewhere. This change ensures that each test scenario gets
the correct parameters passed through. It also generally cleans up the
process for building the test environment to let ansible-galaxy do its
thing. This will make sure the correct version of dependencies get
installed.
