add support for scientific linux
I want to control the database

1) I might want to call it something else
2) I might want to put it on a real database server, and not on the puppet master
3) I might want to combine the 'puppetmaster' role with other roles on a single server and not have resource collisions
Use the agent certificates

This allows a puppetmaster to be a subordinate of another, one without its own
CA which delegates that role.
