KIP-339 — Create a new IncrementalAlterConfigs API

Accepted Kafka 2.3 AdminProtocol

Introduces an IncrementalAlterConfigs RPC that supports SET, DELETE, APPEND, and SUBTRACT operations on individual config keys rather than replacing the entire config. The existing AlterConfigs RPC is a full replace — callers must first DescribeConfigs to avoid accidentally resetting unknown keys — making concurrent config changes from multiple clients unsafe and error-prone.
