Remove unused code paths

[aweiteka]

Looking through the code I don't see that anyone is using several parts of the code. I think we should remove the following. This work is a dependency of #83

config/uat.cfg.sample lines 17+
environment.py lines 53-105

features/cdk
features/examples

steps/vagrant.py
steps/openshift.py
steps/satellite.py
steps/github.py it wouldn't hurt to leave this one

@whitel is the vagrant stuff in use? Please weigh in on this issue.

I thought this project was dead per: #39. Largely my stuff has been abandoned awaiting some magical day when I can figure out CTF or some other way forward. That said, the vagrant steps should be pretty generic and reusable if you so desired.
