fix: Stop using orderId as ID of resources created via an order, use serviceName instead

[amstuta]

Description

Resources that are created using an order used the orderId as ID. This is impractical and forces the users to retrieve the order ID to import the resources. This PR changes this to use the service_name as ID of these resources.

It also avoids making many calls in Read/Update/Delete functions to retrieve the service name each time.

• Improvement (improve existing resource(s) or datasource(s))
