Summary of Changes

Hello @shunping, 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 targeted logging enhancements within the Apache Beam Python SDK. The primary goal is to provide more visibility into pipeline configuration and gRPC server setup, which will be instrumental in diagnosing and resolving issues, particularly those related to gRPC communication during test execution. These changes are purely for debugging and do not alter the functional behavior of the pipeline.

Highlights

• Enhanced Debugging: Added new logging statements to output pipeline options and the runner class during pipeline execution, as well as gRPC server options during initialization, to assist in debugging gRPC-related errors and pipeline configuration.
• Code Readability: Minor formatting adjustments were made to docstrings by removing extraneous blank lines.
