Ensure HTTP application routing has been disabled for Azure Kubernetes Cluster

The 'http_application_routing' add-on is designed to let you quickly create an ingress controller and access your applications. This add-on is not currently designed for use in a production environment and is not recommended for production use.

In Azure Console -

1. Open the Azure Portal and go to Kubernetes Services.
2. Choose the cluster you wish to edit.
3. Under Settings, choose Networking.
4. Under Traffic Routing, uncheck the box for Enable HTTP application routing.

In Terraform -
For current Azure Provider versions:

1. In the azurerm_kubernetes_cluster resource, set the field http_application_routing_enabled to false.

For Azure Provider versions prior to 2.90.x:

1. In the azurerm_kubernetes_cluster resource, if there's an addon_profile block that contains an http_application_routing block, remove the block.
2. Alternately, set the field http_application_routing.enabled to false.
