    firewall: stop using stdlib stages

    Using Puppet stdlib in TripleO is risky because it exposes deployments
    to dependency cycles in the catalog.
    We should rather use native functions to make orchestrations, like
    ordering and dependencies management.

    This patch:

    - removes usage of stages from stdlib
    - use ordering to make sure we run pre rules before post
    - use ordering to make sure we start all Services in catalog before post
      rules. It ensure that we don't drop all traffic before starting the
      services, which could lead to services errors (e.g. trying to reach database
      or amqp)
