Add dport/sport parameter to firewall rule

The port parameter to puppetlabs-firewall is actually deprecated[1].
This adds support for using the new parameter names dport and sport. The
port parameter is still retained in puppet-tripleo for backwards
compatibily for anyone using that interface. It is marked deprecated in
the documentation, however no deprecation warning is needed because
there is already a warning from from puppetlabs-firewall.
