Feature/fedimg meta

This is my go at some meta code for [Fedimg](https://github.com/fedora-infra/fedimg). It works with [this file in Fedimg](https://github.com/fedora-infra/fedimg/blob/develop/fedimg/messenger.py). Let me know if anyone has improvements or suggestions to either file.
You can just put yourself here and remove Luke and I.  We didn't have any part in writing this file.. ;)
