Dubbo GSoC 2023 - Dubbo usage scanner

As a development framework closely related to users, Dubbo provides many functional features (such as configuring timeouts, retries, etc.). We hope that a tool can be given to users to scan which features are used, which features are deprecated, which ones will be deprecated in the future, and so on. Based on this tool, we can provide users with a better migration solution.
Suggestion: You can consider based on static code scanning or javaagent implementation.

https://issues.apache.org/jira/browse/DUBBO-108

The issue names no repository files, tests, or entry points. Begin by evaluating whether static code scanning or a Java agent best detects Dubbo feature usage, including settings such as timeouts and retries. Done means reporting used, deprecated, and soon-to-be-deprecated features and providing a basis for migration guidance.
