- add `set -e` to make failing commands bail the script
- remove trailing `exit 0` which is just extraneous anyhow
- adjust `status_of_proc` options to pass in `$DOCKER_DESC` so we get consistently styled messages like `Docker is running` or `Docker is not running` or `could not access PID file for Docker`

We use the start-stop-daemon pid creation mechanism in addition the intrinsic built into docker. This means the pid file is guaranteed to be written out by the time the script exits.
See #6184.

It's fine to list both here because "Should-Start" is a loose binding (ie, if the listed service exists, it'll be started first, but otherwise, this one will start without it).
