Prior to this commit, the module always attempted
to restart the puppet master service whenever it
managed the master config files. This commit
disables that behavior since our acceptance nodes
don't have the service installed.
Prior to this commit, if you allowed the puppetdb module
to manage postgres for you, it would always try to manage
the firewall for the postgres port on redhat systems.
This commit exposes that as a parameter in a few more
spots, and passes it through to the postgres module.
