allow users to launch the container with a custom command 

The `app-entrypoint.sh` performs the container setup bits only if the
specified command is prefixed with `bundle exec`. In other cases the
specified command is launched without any container initializations.

f.e. `docker run -it --rm express bash` will start the `bash` command
inside the container.
