Title:
  adding additional subnets fail as no network segment is assigned to
  the default subnets

Status in neutron:
  New
Status in tripleo:
  Fix Released

Bug description:
  When adding new subnets to an existing network the network_data.yaml
  like e.g. storage_cell1:

  - name: Storage
    external_resource_network_id: 182e1de2-8e0d-44f9-929d-ebcc1899e46c

    ip_subnet: '172.16.1.0/24'
    allocation_pools: [{'start': '172.16.1.4', 'end': '172.16.1.250'}]
    ipv6_subnet: 'fd00:fd00:fd00:3000::/64'
    ipv6_allocation_pools: [{'start': 'fd00:fd00:fd00:3000::10', 'end': 'fd00:fd00:fd00:3000:ffff:ffff:ffff:fffe'}]
    mtu: 1500
    subnets:
      storage_cell1:
        vlan: 31
        ip_subnet: '172.17.1.0/24'
        allocation_pools: [{'start': '172.17.1.10', 'end': '172.17.1.250'}]
        gateway_ip: '172.17.1.254'
  ...
  - name: InternalApi
    external_resource_network_id: 348b8a30-e11b-4eaa-9843-e46ff071f211

    name_lower: internal_api
    vip: true
    vlan: 20
    ip_subnet: '172.16.2.0/24'
    allocation_pools: [{'start': '172.16.2.4', 'end': '172.16.2.250'}]
    ipv6_subnet: 'fd00:fd00:fd00:2000::/64'
    ipv6_allocation_pools: [{'start': 'fd00:fd00:fd00:2000::10', 'end': 'fd00:fd00:fd00:2000:ffff:ffff:ffff:fffe'}]
    mtu: 1500
    subnets:
      internal_api_cell1:
        vlan: 21
        ip_subnet: '172.17.2.0/24'
        allocation_pools: [{'start': '172.17.2.10', 'end': '172.17.2.250'}]
        gateway_ip: '172.17.2.254'

  The stack deploy fails as the additional subnets get assigned to a
  segment [1], but the default subnets are not and the segment id is
  none:
