Create Microsoft provided container images with diagnostic tools pre-installed

## Background and Motivation

We've had issue https://github.com/dotnet/diagnostics/issues/344 going for a long time tracking getting single file distributions of our tools easily downloadable for production machines. We are the cusp of completing it and looking into what next steps we should be taking to continue improving our acquisition story.

## Proposed Feature

Many of our customers would appreciate if there were pre-canned container images available from Microsoft that had recommended diagnostic tools pre-installed. When an issue later occurs in production the support engineers would already have all the tools ready for use. There are several potential deployment options we could explore:
- An image that has only the diagnostic tools, deployable as a side-car
- Changing the existing runtime container image to include these tools by default
- Creating a new image that has runtime+tools installed together
