Tutorial for creating an application and build on openshift v3

This tutorial will continue to evolve to include things like deployments, deployment triggers, and private docker registries.

I feel like this section is less important than the walkthrough - i.e. if the point is to be an example, why not spend more time in the next section (the explanation, walkthrough), and cut this down to the bare minimum ("Hey, if you don't really want to actually try this or learn anything, just run this script!").  I think the scripting is mostly to work around the gaps in our flow, and as soon as deployment lands, and triggers are configured correctly, this should be empty.
