Docker containers not cleaned up properly and we run out of space

Context

It seems that running benchmarks "can" create a litany of docker containers that are not cleaned up. "docker container ps -a" will show them all and "docker system prune -a" will cleanse, but this "should" be done automatically.

Task Description

• Investigate why docker containers are being left littering dev. machines.
• Put in place what is necessary to clean up properly after benchmark running.

Acceptance Criteria

No extraneous docker containers should be resident on host machines after benchmarks run.
