Misleading error message for failed step

[emgrasmeder]

If I add a cmd into a step and it fails, the resulting error message is not really indicative of the actual problem.

Here's the relevant logs from the container after a failed request: (Note the cmd: "pip99" "install" "-r" "requirements.txt" - probably failed with something like command not found: pip99). We should see the command not found: pip99 message more prominently than (or entirely in place of) HTTP Error: 400

This is caused by a bad request via clj-docker-client with a non-existent path as CMD to the docker daemon which responds with a 400. We should read the response body not just the status code.
