Reorg bootstrap

Reorganize the bootstrap recipes to move the provisioner and squid proxy into the converge phase.

Split out the recipes into a database, core, and node recipes.
Add scripts to run each of those phases independently.

Add some helper scripts that I had lying around that might be useful to complete/update at some point.

There is more to do, but this is a start and I want to get feedback.
Hardcoding these numbers is probably a Bad Idea
