  Utility stack to convert an array of services into a set of combined
  role configs.

parameters:
  Services:
    default: []
    description: |
        List nested stack service templates.
    type: comma_delimited_list
  ServiceNetMap:
    default: {}
    description: Mapping of service_name -> network name. Typically set
                 via parameter_defaults in the resource registry.  This
                 mapping overrides those in ServiceNetMapDefaults.

    description: Mapping of service -> default password. Used to help
                 pass top level passwords managed by Heat into services.
