This proposal adds new option to each commands only, so existing users can use all commands w/o changes.

Rejected Alternatives

Adding version option to each command parsers

Kafka's commands have option parser for each. This approach is to update each option parser.
For adding this option to kafka-topic.sh, we should modify TopicCommandOptions class, for example.

Pros

• show up this option in help describe

Cons

• need to maintain individually for this option when anyone add and update commands
