Feature Request: Automated core dump collection for Azure Devops Docker-container builds

• This issue is blocking
• This issue is causing unreasonable pain

Filed on behalf of @ViktorHofer after investigating this build (attempt 1)

In this scenario, the build occurs inside an Ubuntu 18.04 docker container, and crashes with a segmentation fault. Were this build running directly on a Helix buildpool.ubuntu machine it would likely have uploaded a core dump from the build, but since this is inside a container we don't actually control (controlled by Azure DevOps agent) we can't help this.

We could possibly set up core dump collection inside these containers (perhaps with a specially named folder), and provide a common Arcade functionality to upload any dumps found in said folder as artifacts of the build; if this works, users could investigate their one-off crashing .NET core builds.
