masquerade: stop using YAQL for iptables data

See https://bugs.launchpad.net/tripleo/+bug/1760211 but the YAQL + Heat
format hasn't helped us to build the data needed by Puppet to create
IPtables rules for masquerading.

We'll solve it in puppet-tripleo with native hash iterations, so for
that we just export MasqueradeNetworks to Hiera and we'll use this data
from the puppet module directly.
