update puppet params to use new network config

re-run 'rake db:seed' with this commit, as many of the defaults have changed.

In addition, delete and recreate any deployments you may have, as the VIPs
have changed (there's one more change coming that will refactor VIPs even more
extensively though)
@ares -- sure. This is largely code moved over here from elsewhere (we weren't showing exceptions before either). If there are no controllers, should this throw an exception, or should it just return nil though?
