Title: Use sudoers.d for kitchen user permissions

Since test-kitchen is used to test chef recipes, it is possible that the sudoers file could be modified or rewritten during a recipe run. This means that the sudo permissions of the kitchen user can be overwritten. If the permission is instead included in a separate file in the /etc/sudoers.d directory, no chef recipe should be able to remove those permissions.
