Configure all VIPs including those on custom composable networks.
Hard-coded network names are removed and instead a hiera parameter
containing all networks is used.
For keepalived, the vrouter_id is generated from an index for each
network in the hiera data. This will change the vrouter_ids for
some VIPs.
