Publishing a client to pypi

[foxish]

If the operator were used to generate an openapi spec, and publish a python client, that may help interactive users invoke the distributed training CRD in an easier fashion.

The flow I imagine is something like:

pip install tf-k8s-operator
...
import tf.k8s.operator
operator.training.New(...params here...) #creates the CRD behind the scenes

Saw this is a dupe of #167. Closing.
