GA：Azure Kubernetes Service (AKS) support for 5K Node

AKS now supports cluster scale beyond the 1000 node limit in the  Standard tier. You can now scale your clusters beyond 1000 node limit up-to a maximum of 5000 out of the box without requesting any limit increases or special enablement.

Both existing and new AKS clusters using the Standard tier now get greater scalability and performance for Kubernetes control plane, up-to a maximum of 5000 nodes and 100,000 pods per cluster. This will help you run larger workloads and get greater scaling performance of the Kubernetes deployments and allow you to consolidate your AKS clusters and get better control plane reliability at scale.

To increase the node limit beyond 1000, you must have the following pre-requisites:
1. An existing AKS cluster that needs the node limit increase. This cluster shouldn't be deleted as that will remove the limit increase.
2. Clusters using the Standard tier.
3. Clusters using Kubernetes version 1.23 or above.
