Validate installed packages against actual product dependencies #2618
Description
Summary
The packages that are installed by Dockerfiles are defined independently of what the product's actual dependencies are. These should be in sync such that if product dependencies are changed in any way, the Dockerfiles will reflect that change. Today this is a manual process but it can be improved through the work being done in dotnet/core#5651.
Goal
Contributors can use automation to validate that the Linux packages installed in Dockerfiles match up with the official product dependencies.
