[Bug]: Logs are not printed out in headless command line mode

Is there an existing issue for the same bug?

Describe the bug and reproduction steps

Currently, in headless command line mode, logs of what the agents are doing is not printed out. This should be fixed.

To do so, it'd be good to first look at the documentation for headless mode, and then find a good place to add a subscription to the event stream like the following:

    async def on_event(evt):
        logger.info(evt)
    runtime.event_stream.subscribe(EventStreamSubscriber.MAIN, on_event, str(uuid4()))
