…eams (KIP-698) Implements KIP-698 to prevent silent data loss when internal topics (repartition/changelog) are accidentally deleted. New public API: - KafkaStreams#init() and init(InitParameters) to explicitly create and validate internal topics before starting the application - InitParameters with fluent builder (following CloseOptions pattern): timeout(), withTimeout(), enableSetupInternalTopicsIfIncomplete() - StreamsConfig 'internal.topics.setup' config: 'automatic' (default, backward compatible) or 'manual' (requires init(), throws on missing topics during rebalance) New exceptions (already merged via apache#19988): - MissingInternalTopicsException - MisconfiguredInternalTopicException - InternalTopicsAlreadySetupException Behavioral changes: - In manual mode, makeReady() throws MissingInternalTopicsException when topics need creating during rebalance (instead of silently recreating them) - init() validates state (CREATED only), source topics, internal topic existence and configuration - INTERNAL_TOPIC_SETUP_CONFIG forwarded to consumer configs for the partition assignor Reviewers: Matthias J.
