Chef 12 support

[mdavidn]

Someone new to Chef might run the following commands to install knife-cloudstack-fog.

#!/bin/sh
curl -L https://www.chef.io/chef/install.sh | sudo bash
sudo /opt/chef/embedded/bin/gem install knife-cloudstack-fog
/opt/chef/bin/knife --help

This produces a broken Chef installation. The help command dumps the following RubyGems trace. The Chef installer ships with chef 12.3.0 and rake 10.1.1 and activates those versions before loading knife-cloudstack-fog 0.6.0.

I've just starting working with Chef 12 and have encountered this myself. I'll dig in and see if this is a quick fix.

Okay, I've updated the gemfile to remove those dependencies and the plugin appears to be working for me with ChefDK.

Can you pull and build the gem from git and test it against your environment to see if it works for you?

I built the gem from source, and it works, but I had to install fog by hand. I'm testing with the chef-client installer rather than the full ChefDK.
