Simplify dealing with $::platform_services::manage_front_ips

The way $:::platform_services::manage_front_ips has been used in past
was rather complicated. In fact we only need a way to disable accessing
cloudstack in our vagrant setup (which SRF uses for local development).
Do not export cloudstack port-forwardings if $::platform_services::manage_front_ips is false
Merged in mmz-srf/puppet-platform-services/feature/simplify-dealing-with-manage_front_ips (pull request #22)
