Summary of Changes

Hello @tarun-google, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request delivers a new Dataflow Flex Template designed for streaming data from Kafka to Iceberg. The template leverages YAML for its definition, providing a clear and structured way to configure the streaming pipeline. It includes comprehensive parameter definitions and an integration test to validate its robust operation.

Highlights

• New Dataflow Flex Template: Introduced a new Dataflow Flex Template for streaming data from Kafka to Iceberg, defined using YAML.
• Template Parameter Definition: Added a new Java interface, KafkaToIcebergYaml, to formally define all the necessary parameters for the Kafka to Iceberg streaming pipeline.
• Pipeline Configuration: Created KafkaToIceberg.yaml which outlines the pipeline's structure, utilizing ReadFromKafka and WriteToIceberg transforms, and maps the defined parameters.
• Kafka Options Definition: Added kafka_options.yaml to specifically define the Kafka-related parameters for the template.
• Integration Test: Included a new integration test, KafkaToIcebergYamlIT.java, to ensure the end-to-end functionality and correctness of the Kafka to Iceberg YAML template.
