General availability: AKS auto-certificate rotation

Azure Kubernetes Service (AKS) uses certificates for authentication with many of its components. Periodically, you may need to rotate those certificates for security or policy reasons. AKS will now automatically rotate non-CA certificates on both the control plane and agent nodes before they expire with no downtime for the cluster. AKS auto-certificate feature is currently available in the following regions: * East US 2 Early Updates Access Program (EUAP) * Central US EUAP * West Central US * UK South * East US * Australia Central * Australia East This capability is being rolled out to other regions and will become available in the remaining Azure regions by end of Feb 2022.
