Ensure auto renew of certificates is turned off for Azure App Service Certificate Order

When an App Service Certificate is renewed, all the corresponding App Service SSL bindings are updated automatically, this may lead to dangling certificates in Azure App Service Certificate Order.

In Azure Console -

1. Open the Azure Portal and go to App Service Certificates.
2. Select the App Service Certificates you wish to edit.
3. Set Auto renew to Off.

In Terraform -

1. In the azurerm_app_service_certificate_order resource, set auto_renew to false.
