Pull Request Overview

This PR adds support for source and sink connectors in Pulsar functions, enabling functions to use external connectors (e.g., Kafka, Kinesis) as inputs/outputs instead of traditional Pulsar topics. It also adds configurability for Java instance runtime parameters.

Key changes:

• Added SourceConnectorSpec and SinkConnectorSpec types with fields for connector configuration including className, configs, and type information
• Extended validation logic to skip input/output topic validation when connectors are configured
• Added logic to inject connector configuration into function specs and command-line arguments
• Added instancePath and entryClass fields to JavaRuntime for runtime customization
