Harini Rajendran 4ff6026d30 Adding SegmentMetadataEvent and publishing them via KafkaEmitter (#14281) ... In this PR, we are enhancing KafkaEmitter, to emit metadata about published segments (SegmentMetadataEvent) into a Kafka topic. This segment metadata information that gets published into Kafka, can be used by any other downstream services to query Druid intelligently based on the segments published. The segment metadata gets published into kafka topic in json string format similar to other events.		2023-06-02 21:28:26 +05:30
