In 4.2, one was able to decorate a transport and hook into `TransportInterface::stop()` to perform some business tasks when the `messenger:consume` process gets killed.
In 4.3 the `stop()` logic has been moved to `Worker` which cannot be decorated when used via `messenger:consume`.
This PR adds a marker event dispatched when the worker is stopped to provide the same capability.
Briefly discussed with @weaverryan.
My use case:
I have a temporary CSV file locally which grows while consuming jobs.
This file is uploaded to AWS S3 and squashed once a while (every 5minutes). It is also uploaded when the `messenger:consume` process gets stopped (to store the remaining lines).
For the former (time-based upload), I can listen on `WorkflowMessageHandledEvent` to make the upload happens in case the 5 minutes delay is elapsed. This solves the latter.
