[KNIFE-330] I wrote some initial specs for this plugin

http://tickets.opscode.com/browse/KNIFE-330

I started writing some specs for this plugin. They're not complete yet, and they currently rely on a small fix that needs to be incorporated into chef and some mock classes that need to go into fog. I've submitted both of those to their respective upstreams, just waiting on new releases.

I thought I'd go ahead and create this now though to have a place to track it.

Let me know if I should do something else.
