Set ip_version property in the subnets section in DeployedServerPortMap
set up in the environment for Undercloud and Standalone deployments.
This will ensure that the NetIpVersionMapValue is populated properly,
and puppet parameters like 'rabbit_ipv6' will be correctly populated
for IPv6 undercloud deployment.
