When first setting up a project, properly setting up your config files can have a bit of a learning curve

When first standing up this project I ran into an issue where my hardware did not support hardware virtualization and thus I couldn't use KVM. When going into the nova.conf I noticed that it makes sure to mention that you should not edit those config files as the changes will be overwritten by Chef. This commit documents how you can tweak your configuration and push it out to your nodes using chef-server so the changes will not be overwritten.
