Mcquin/kitchen with travis

OH NO WHATS GOING TO HAPPEN
i think you want to make your .kitchen.yml look a bit more like this one:

https://github.com/lamont-granquist/sk_ruby/blob/master/.kitchen.cloud.yml

require_chef_omnibus needs to be moved to the `provisioner:` block (or dropped because you're rocking the git_sha stuff?)
the aws-specific stuff should all be moved to a global `driver_config:` block or be under the individual platforms.

instead of having a gobal `driver:` section we also seem to usually put that on each `platform` as a `driver_plugin` option so that we could switch individual platforms between EC2 or Digital Ocean and use both in the same kitchen config...
