Uncouple from the puppet_litmus gem

[h0tw1r3]

Requesting feedback

Transforms this pseudo puppet module (which requires a gem not bundled with anything) into an standard r10k/bolt installable module usable outside of the litmus framework.

Module is very useful outside of litmus, particularly for real-time puppet code development. Provision a node, do some "live" development and testing, tear it down.
