    [OVS] Network segmentation ID change not allowed if multisegments
    
    If a network has several segments, the provider network segmentation ID
    cannot be changed. This is defined in the feature spec [1].
    
    In the case of having a multisegment network, the OVS agent RPC call
    "get_network_details" will return the following value:
    
      {
        "network": {
          "updated_at": "2019-02-19T13:25:15Z",
          "revision_number": 5,
          "id": "ba973781-065b-4c69-9f07-a5c4f9a3b754",
          ...
          "segments": [{
            "provider:network_type": "vxlan",
            "provider:physical_network": null,
            "provider:segmentation_id": 10041
          },
          {
            "provider:network_type": "vxlan",
            "provider:physical_network": null,
            "provider:segmentation_id": 10066
          }],
          ...
    }
    
    The provider network information will be contained inside the "segments"
    list, instead of being container in the parent "network" dictionary.
