AZU007 - Ensure RBAC is enabled on AKS clusters

Using Kubernetes role-based access control (RBAC), you can grant users, groups, and service accounts access to only the resources they need.

The following example will fail the AZU007 check.

resource "azurerm_kubernetes_cluster" "bad_example" {
	role_based_access_control {
		enabled = false
	}
}

The following example will pass the AZU007 check.

resource "azurerm_kubernetes_cluster" "good_example" {
	role_based_access_control {
		enabled = true
	}
}
