Summary of Changes

Hello @Yuan325, 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 significantly refactors the internal Serverless Spark tools by abstracting their dependency on the concrete serverlessspark.Source implementation. By introducing a compatibleSource interface and dynamically retrieving source information, the changes enhance modularity and reduce tight coupling, making the tools more flexible and easier to maintain. This refactoring ensures that tools interact with sources through a well-defined contract, improving the overall design of the system.

Highlights

• Decoupling Source Configuration: The pull request decouples the direct dependency of Serverless Spark tools on the serverlessspark.Source type, promoting a more modular architecture.
• Introduction of compatibleSource Interface: A new compatibleSource interface has been introduced in the Serverless Spark tools, defining the necessary methods (GetOperationsClient, GetBatchControllerClient, GetProject, GetLocation) that tools require from a source.
• Dynamic Source Retrieval: Tools now retrieve their associated source dynamically via resourceMgr.GetSource() and cast it to the compatibleSource interface, rather than holding a direct reference to a concrete serverlessspark.Source.
• New Methods in serverlessspark.Source: The serverlessspark.Source struct now includes GetProject() and GetLocation() methods to expose project and location details, which are utilized by the refactored tools.
• Updated Tool Method Signatures: The RequiresClientAuthorization and GetAuthTokenHeaderName methods in the Serverless Spark tools have been updated to return an error in addition to their previous return values, aligning with a common pattern for operations that might fail.
