Alex Vandiver c9141785fd puppet: Use concat fragments to place port allows next to services.
This means that services will only open their ports if they are
actually run, without having to clutter rules.v4 with a log of `if`
statements.

This does not go as far as using `puppetlabs/firewall`[1] because that
would represent an additional DSL to learn; raw IPtables sections can
easily be inserted into the generated iptables file via
`concat::fragment` (either inline, or as a separate file), but config
can be centralized next to the appropriate service.
