Cleaning up devicemapper Docker

Just run these three. No need to remove RUNNING containers.

Cleanup exited processes:

docker rm $(docker ps -q -f status=exited)

Cleanup dangling volumes:

docker volume rm $(docker volume ls -qf dangling=true)

Cleanup dangling images:

docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
