Initial habitat planadamhjk/habitat

This is a simple initial habitat plan. It creates a chef-client service,
which uses chef-solo to run cookbooks that are located in the default
cache location.

To build it yourself:

* Install habitat
* `hab studio build`

You'll wind up with a habitat artifact in `results`.
