Ensure that Azure CNI Networking is enabled

Azure CNI networking for production allows for separation of control and management of resources. From a security perspective, you often want different teams to manage and secure those resources. With Azure CNI networking, you connect to existing Azure resources, on-premises resources, or other services directly via IP addresses assigned to each pod.
