Support GCP gVNIC interface 7.0.1

The new GCP gVNIC interface is supported, which offers improved performance and bandwidth and is required on some VM shapes tuned for optimal performance.

A VM with gVNIC must be deployed with the CLI or API. Refer to the Using Google Virtual NIC documentation for other limitations. If you are upgrading from prior images that support virtIO, the images will remain that way.

Refer to Creating a VM that uses gVNIC for detailed instructions. The following example shows sample commands used to create an instance.

To deploy a gVNIC with the gcloud CLI:

1. Create a gVNIC enabled image using the FortiGate marketplace image.

   gcloud compute --project=dev-project-000-000000 images create gcp-ond-700-gvnic --source-image=fortinet-fgtondemand-700-20210407-000-w-license --source-image-project=fortigcp-project-000 --guest-os-features=GVNIC

2. Deploy the instance with the gVNIC image and gVNIC specification in the parameter:

   gcloud compute --project=dev-project-000-000000 instances create xxxxxx-script-ond-0128-gvnic --zone=us-central1-c --machine-type=n1-standard-1 --network-interface nic-type=GVNIC,subnet=xxxxxx-hapvc-port1external,private-network-ip=10.0.0.15,address=**.**.**.*** --network-interface nic-type=GVNIC,subnet=xxxxxx-hapvc-port2internal,private-network-ip=10.0.1.15,no-address --can-ip-forward --maintenance-policy=MIGRATE --service-account=************-compute@developer.gserviceaccount.com --scopes=https://www.googleapis.com/auth/cloud-platform --image=gcp-ond-0128-gvnic --image-project=dev-project-000-000000 --boot-disk-type=pd-standard --boot-disk-device-name=xxxxxx-script-ond-0128
   Created [https://www.googleapis.com/compute/beta/projects/dev-project-000-000000/zones/us-central1-c/instances/xxxxxx-script-ond-0128-gvnic].
   NAME                          ZONE           MACHINE_TYPE   PREEMPTIBLE  INTERNAL_IP  EXTERNAL_IP   STATUS
   xxxxxx-script-ond-0128-gvnic  us-central1-c  n1-standard-1               10.6.30.5    **.**.**.***  RUNNING

3. Verify that gVNIC is enabled for the NIC:

   gcloud compute instances describe xxxxxx-script-ond-0128-gvnic --zone=us-central1-c
   …
   guestOsFeatures:
   - type: GVNIC
   …
   name: xxxxxx-script-ond-0128-gvnic

   …

4. Log in to the FortiGate using SSH and verify that the drivers are correct:
