Refactor into template

As is described in the Readme, the control-repo which initially began as a template and starting-point for R10k slowly began accumulating more opinionated code in the form of profiles, modules, and Hiera data. The 1.0.0 release of control-repo represents a return to its roots of being a minimal template for the purpose of getting started with R10k and Code Manager. All the code that used to be in the control repo still exists if you're looking for it - check out the Readme for direct links.
