Unfortunately we can't do changes to binary format of JobConfig. The class must be backwards compatible because it's stored as a part of JobRecord and a cluster must be able to deserialize it after a rolling upgrade. It also can't use Versioned, because it's also sent in binary form from the client (see #20755). Therefore we can't do incompatible changes until the next major release.

@viliam-durina
Thanks.
This PR will be opened then. Before a merge I'll adapt it to any changes/new requirements, if needed

@awelless Is there any chance you could join our community Slack channel ? -- there's a link to do so here https://hazelcast.com/dev-community/.
We'd like to chat to you to find out if there's a way we can implement this feature somehow

This can be achieved currently by using JobConfig.setArgument. It's not perfect but can be used to pass some extra data about the job.

I'll add a comment to #20510 discussing the motivation.

This fix seems pretty good, perhaps the wider problem is that Jet config does not support easy extension as new fields are required

Being able to describe jobs using a description field remains a useful need.
