Create AKS cluster fails on 2.4.0

Describe the bug

AKS cluster creation failed after upgrade of az cli from 2.2.0 to 2.4.0

To Reproduce

Run AKS cluster create

az aks create --name gleb-aks-bkp-atom-hero --resource-group cluster-name --node-count 5 --generate-ssh-keys --vm-set-type VirtualMachineScaleSets --enable-addons monitoring --service-principal <service-principal> --client-secret <client-secret> --kubernetes-version 1.14.8 --node-vm-size Standard_DS3_v2

Expected behavior

Cluster gets created

Actual result

The behavior of this command has been altered by the following extension: aks-preview
The request content was invalid and could not be deserialized: 'Could not find member 'template' on object of type 'DeploymentDefinition'. Path 'template', line 1, position 12.'.

Environment summary

OS Linux Ubuntu 18.04 azure-cli 2.4.0

This command does work when az cli version is

2.2.0 *

This should be fixed in the latest extension version 0.4.44.

 az extension update --name aks-preview

Please report back if that fixes the issue.
