WIP: LISA conference hacking

@reset Review when you get a few cycles. This isn't finished yet. Internet is slow here so I can't yet confirm or deny that the tests are passing. 

1. Adds a chef-provisioning recipe for a simple bootstrap cluster.
2. Adds a few platforms to Kitchen tests, and a source test.
3. (Hopefully) fixes #41.
4. Cleans up a few bits.
