[Question] config 操作问题 以及 config 顶层设计问题

### Search before asking

- [x] I had searched in the [issues](https://github.com/apache/eventmesh/issues?q=is%3Aissue) and found no similar issues.

### Question

问题：不同的 metadata 与 不同的组件，config 的行为不一样。比如 RocketMQ Topic 与 kafka topic 的 config 的行为基本不一样

PS:
（1）分析全面分析现在的 组件的 metadata 的config 详情与行为

The issue names no files, tests, or entry points. Begin by locating the configuration handling for component metadata, then compare the existing RocketMQ topic and Kafka topic behavior. Done means producing an agreed top-level configuration design that accounts for the differing component behaviors.
