Currently docker entrypoint is a bash script. `docker stop` command (or restart in kubernetes) sends SIGTERM to the container but it isn't catched by gunicorn. So gunicorn can't start graceful shutdown which may lead to killing user's connection and also adds 10s (default value) delay for stopping until docker sends SIGKILL. Using `exec` replaces the shell with the process being opened and signals are propagated correctly.
