Merge pull request #120 from intercity/add-test-kitchen

Add test kitchen and tests for nginx, mysql and application configs
Update test-kitchen readme
Add version 0.1.0 of sysadmins: a way to add sudo users
Make sudo work like Ubuntu's defaults.

* Use a group called "admin"
* Require a password for sudo.

Requiring a password breaks Vagrant's provision and setup
and as such, we don't require a password in Vagrant.

Quoting according to houd-ci with double (") quotes
Make username the key of the list of sysadmins.
