Add Production Environment

[dkurepa]

Most of these issues are described in https://github.com/dotnet/arcade-services/milestone/39. This mainly includes:

• Creating all Azure Resources in the production subscription (using the bicep script)
• Creating all needed Service Connections
• Changing the CI to release already built and tested containers, from the Staging environment
• Configuring E2E tests to work with the new infra

As an example, this is a service ticket opened for INT PCS MI to be added to DevDiv: https://devdiv.visualstudio.com/DevDiv/_workitems/edit/2221593

A new one can be opened here: https://aka.ms/vsengticket

We'll also have to add a few Managed Identities to the AzDo project:

• ProductConstructionProd (needs to have the same permissions as Maestro)
• FeedCleanerProd (needs to be added to https://dev.azure.com/dnceng/internal/_settings/permissions?subjectDescriptor=vssgp.Uy0xLTktMTU1MTM3NDI0NS0xMzQ5MTQwMDAyLTIxOTY4MTQ0MDItMjg5OTA2NDYyMS0zNzgyNDgyMDk3LTEtMjMzNTMyMDA4Ny0zMDMyNTUyNzcyLTMxNTMyMDE5NTgtMTgyNTMxMTU2MQ)
