Thanks, I keep meaning to automate these and/or update the templates but this will do in the meantime.

A few things:

• max.poll.records is a consumer setting, that doesn't belong in server.properties.
• group.max.session.timeout.ms isn't directly a ZooKeeper setting—would you mind adding a new section something like "Additional Broker Settings" at the end? controlled.shutdown.enable can be moved there too, don't know why it ended up there.
