Add Message Token as field to Slack message

[AmirSasson]

today, only the Level and the Timestamp are hard coded sent to slack.
what if my log message look like this:
_logger.LogInformation("{ClientIp} has Joined", IP);
i would expect to have another field ClientIp (the same as ElasticSerach Sink does).
any chance to have this in the next drop?

This functionality is already present - at least at the time of writing. Considering that this request is very old, I am closing this for now.
