[Feature Request] Support dotnet OOB tools operating across a container boundary

[noahfalk]

Currently all our tools take a -p proc_id argument to specify the process to connect to. When running multiple docker containers and observing the processes from the outside the list-process / ps command will show multiple processes with ID 1 and trying to connect will fail because it is ambiguous. It would be nice if there was some way to disambiguate and connect. See #589 for a clear example of this.

Yes, this is my current use case: A docker-compose with dotnet webapi, webmvc and services.
