Description

Resolves https://github.com/confluentinc/cp-demo/issues/371

Delegates error messaging to the behavior of docker -ps CLI which results in kevinblaisdell@manta scripts % ./start.sh Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Can be removed in the future if docker CLI commands gracefully handle this consistently as docker -ps does.
