Rename Workflow Class

[ms-k1ngk0ng]

As pointed out, Workflow means something specific and naming a class with this will make things increasingly more confusing.

This one is pretty self-explanatory. I was taking the term blueprint out for a spin and may have merged some commits that use it as a replacement for workflow. But, ultimately it's going to be up to y'all. I think what is most important is using a word that emphasizes the spirit of what the workflow is doing -- it's essentially a boiled-down encapsulation of all that the TestScript achieves. If there's a setup, and if that setup requires storing the response in order to then grab the id from that response, then that's shown in the workflow.
