how to instructions about blacksmith-kubernetes

[ebraminio]

This provides image and other needed things for blacksmith in order to provision a baremetal machine with Kubernetes. Extraction of this from the main project was with this idea in mind that there could be other templates (called workspace in blacksmith sense) for Blacksmith. The blacksmith-kubernetes is highly coupled with the main project, blacksmith, so for a build instruction and getting a general sense I suggest having look at this https://github.com/cafebazaar/blacksmith#cluster-setup which uses both of blacksmith and blacksmith-kubernetes for setting up a virtual kubernetes cluster in your machine.
