Description

I find many JSON-format command line params for example `kafka-reassign-partitions.sh --reassignment-json-file my.json` which we can use JsonConverter to read and write.

However, currently, we use camelCaseName when converting protocol data to JSON, but most JSON-format command line params use snakeCaseName, so we should support snakeCaseName in JsonConverterGenerator.

In the post-KIP-500 world, we will move all configs in zookeeper to kafka-raft, and the data in zookeeper is also stored as snakeCaseName JSON, so it's useful to support snakeCaseName in JsonConverterGenerator in advance.
