AKS vnetSubnetID not filled for agentPoolProfiles

[aristosvo]

Problem

Endpoint returns for my newer AKS clusters no vnetSubnetID in agentPoolProfiles

Endpoint

https://management.azure.com:443 "GET /subscriptions/{subscription}/providers/Microsoft.ContainerService/managedClusters?api-version=2019-10-01 HTTP/1.1"

Response example of a newer cluster

"agentPoolProfiles": [
      {
        "availabilityZones": null,
        "count": 3,
        "enableAutoScaling": false,

Response example of an older cluster (probably created via Azure Portal)

      {
        "availabilityZones": null,
        "count": 3,
        "enableAutoScaling": null,
        "enableNodePublicIp": false,
        "maxCount": null,
        "maxPods": 30,
        "minCount": null,
        "name": "agentpool",
        "nodeTaints": null,
        "orchestratorVersion": "1.15.7",
        "osDiskSizeGb": 100,
        "osType": "Linux",
        "provisioningState": "Succeeded",
        "scaleSetEvictionPolicy": null,
        "scaleSetPriority": null,
        "type": "AvailabilitySet",

        "vnetSubnetId": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupId}/providers/Microsoft.Network/virtualNetworks/{vnetid}/subnets/default"
      }
    ],

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @Azure/aks-pm.

I just check with the following API Version

https://management.azure.com/subscriptions/{subscription}/resourceGroups/{rg}/providers/Microsoft.ContainerService/managedClusters/{cluster}?api-version=2020-03-01

I'm getting the expected value
