Update Quickstart

[jeffmendoza]

A few policies have been added to Allstar since the quickstart was created. Those should be evaluated to see if they should be a part of the quickstart install.

Also, some features like "opt out private" have been added. Those should be turned on for polices where it makes sense (security.md policy for example).
