Compatibility, Deprecation, and Migration Plan

This KIP introduces incompatibility when "print.partition=true" (existing argument). Before this KIP, it prints the partition as a number after the value. After this KIP, it prints the partition prefixed with "Partition:", like "Partition:0" before the key (if printed) and value.

The other changes are backward compatible . If a user won’t because they do not exist before. Apart from "print.partition=true", if a user does not use any new parameters, then the output of console consumer will look the same as before.
