Ingesting from Kafka 8

The previous examples are for Kafka 7. To support Kafka 8, a couple changes need to be made:

• Update realtime node's configs for Kafka 8 extensions
  • e.g.
    • druid.extensions.coordinates=[...,"io.druid.extensions:druid-kafka-seven:0.6.139",...]
    • becomes
    • druid.extensions.coordinates=[...,"io.druid.extensions:druid-kafka-eight:0.6.139",...]
• Update realtime task config for changed keys
  • firehose.type, plumber.rejectionPolicyFactory, and all of firehose.consumerProps changes.
