  Mapping of service_name_network -> network name

parameters:
  ServiceNetMap:
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry. Use
                 parameter_merge_strategies to merge it with the defaults.
                 Note that the key in this map must match the service_name
                 in the service template, e.g if the service_name is heat_api
                 the key must be either heat_api_network, or optionally
                 HeatApiNetwork (which will be internally converted to
                 transform captalization to underscores).

  VipSubnetMap:
    description: Map of (network_name or service_name) -> subnet_name that
                 defines which subnet to host the VIP. Use
                 parameter_merge_strategies to merge it with the defaults.
