Add OpenAPI and Knowledge Base configurations to Xgen settings

- Introduced OpenAPI settings to include base URL configuration.
- Added Knowledge Base settings to capture features, chunkings, embeddings, and converters.
- Enhanced the processXgen function to integrate these configurations into the Xgen settings map, improving extensibility and functionality.
