Seeding of products in shopping cart service does not always work

The seeding in products service does work. But sending the data via kafka to the shopping cart service makes issues, specially for the first startup.
The problem is that the kafka broker sometimes start completly new and all commits are gone. Therefore the created datasets that could not ve been read by the shopping-cart service are gone.

A temporary fix is to clear the Products table in both databases Inventory and ShoppingCart. Then stop all containers with ctr-c and simply up them again with docker-compose up. Do not run docker-compose down. The product service will recreate the products and publsih them correctly to kafka. The shopping-cart service will listen correctly
