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.
Nothing.  It was/is an example script that can be used to what isc dhcp for events of IPs getting assigned.  This with the other scripts were more there for holding so I didn't lose them.  I'll revert out this and the other scripts.
