    Fix RedisVirtualIP when overrdiing InternalApi name_lower

    When overriding RedisVirtualIP name_lower and using the
    service_net_map_replace the overridden name_lower is was
    not used in VipSubnetMapDefaults.

    Get name_lower from the _service_nets jinja2 variable
    which holds the replaced name_lower for the network when
    service_net_map_replace is used.
