 Alternate MySQL backend for Hiera
 
 This is a MySQL backend for Hiera inspired by [hiera-mysql](https://github.com/crayfishx/hiera-mysql). Unfortunately no work has been done to that backend for the past 9 months and it was missing a couple of features I needed so I decided to pick up the torch and implement them myself.
