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.
Not sure what to do about this one.  I want it as part of the provisioner because I don't want the admin node downloading it if it isn't going to need it because it isn't the provisioner.  

That is why I moved it into the provisioner.    For my docker containers, it gets skipped because it is injected in the cached directory.  For RPM installs, you have to eat the time either way.  It seems reasonable given the separation work we are doing, but I can be talked around to a different path.
