Create a bare bones service for the VMR backflow, and make it deployable

[dkurepa]

We want to create a bare bones service that will eventually become the VMR backflow service. We will start with an empty Aspire project, to improve on the local development story. We will also create a bare bones ASPNET API, and add it to the Aspire project.

We also want to create a pipeline that will make this service deployable using the Blue-Green Deployment approach.

In #3172, we added the new Product Construction Service. We chose to use Aspire for better local development support. The system currently consists of an empty API which we'll keep expanding. We have also set up a new pipeline for it's deployment - arcade-service-product-construction-service, using the blue/green deployment approach
