Implement Advanced Firewalling support

* Provide a Define function which will allow to manage IPtables rules.
* Manage rules in 'pre' and 'post' Puppet stages, it allows to create
  rules before and after regular Puppet stages (ie: to make sure no rule
  exists *before* and everything is blocked *after* regular Puppet
  stages)
