In deployment we use docker logs forwarded to journald. I'd really want to log directly into host's journal but that is a task for some other day. Docker logs apparently [1] make the message's severity higher if it is parsed from stderr. Worker will now log WARNING and higher to stderr if invoked with --log-stderr option. We modified spdlog's dist_sink to enable this functionality. Closes #46.
