Summary of Changes

Hello @DDShantanuBadmanji, 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 introduces a significant refactoring to standardize the management and observability of ConfigProvider instances within Kafka, particularly in Kafka Connect. By wrapping ConfigProviders in a new Plugin object, the system gains a consistent mechanism for handling plugin lifecycle events and enables ConfigProvider implementations to register and expose metrics. This change improves the extensibility and monitoring capabilities for custom configuration providers.

Highlights

• Plugin Wrapper for ConfigProviders: ConfigProvider instances are now consistently wrapped in a Plugin object, standardizing their lifecycle management and enabling unified handling across the Kafka Connect ecosystem.
• Metric Registration for ConfigProviders: The ConfigProvider interface now supports metric registration through the Monitorable interface. Implementations can expose metrics, which will be automatically tagged with config, class, and provider information.
• Refactored ConfigProvider Instantiation: The logic for instantiating ConfigProviders in AbstractConfig, MirrorMakerConfig, Worker, and WorkerConfigTransformer has been updated to integrate with the new Plugin wrapper, ensuring proper initialization and metric setup.
• Enhanced Testing for Plugin Management: New and modified test cases have been added to verify the correct behavior of the Plugin wrapper, including the order of configuration and metric registration calls for ConfigProviders.

Code Review

This pull request introduces a significant refactoring to enable metrics for ConfigProvider implementations. The core change involves wrapping ConfigProvider instances in a new Plugin class, which facilitates the integration with Kafka's metrics system. The changes are consistently applied across various components, including AbstractConfig, ConfigTransformer, and the Connect runtime (Worker, Plugins, etc.). The new functionality is well-tested, with new tests verifying both the metrics registration and the correct lifecycle of ConfigProviders (ensuring configure is called before metrics are initialized). The code quality is high, and I have no specific feedback or suggestions for improvement.
