Use Dapr to be able to easily change storage

[henrikrexed]

Feature Request

For each service that interacts with storage—such as CartService, CheckoutService, Accounting, Fraud, and the Product Catalog—we should implement a solution like Dapr. This will allow us to utilize different types of storage. For example, we could replace the JSON file in the Product Catalog with an external database.

What would you like to happen instead? What is the expected behavior?

Implementing Dapr will simplify the process of adding and customizing storage for future releases of the demo. Additionally, we could enable the distributed tracing and metrics capabilities provided by Dapr.
