Chia-Ping Tsai updated KAFKA-16666: ----------------------------------- Description: `GroupMetadataMessageFormatter`[0], `OffsetsMessageFormatter`[1], and `TransactionLogMessageFormatter`[2] are used by ConsoleConsumer to parse data of internal topics. Following the migration plan, we should move them to tools-api module. Also, we need to keep the compatibility of command line. That is to say, `ConsoleConsumer` can accept the previous package name and then use the (java) implementation to parse and make same output.
