### What is this PR for? This PR introduces the initial step of refactoring Zeppelin’s listener-based architecture to an EventBus model([proposal](https://cwiki.apache.org/confluence/x/vAsGFw)). It establishes the necessary infrastructure and refactors the `NoteRemoveEvent` flow as the initial target. Key Changes: - Added `ZeppelinEventBus` class - Added RxJava3 dependency in the `zeppelin-zengine` module - Added `zeppelin.eventbus.enabled` feature flag - Updated `NotebookServer`(implements NoteEventListener) to handle `NoteRemoveEvent` via `ZeppelinEventBus` when `zeppelin.eventbus.enabled` is enabled ### What type of PR is it? Improvement ### Todos * [ ] Refactor other NoteEventListener methods and additional listeners to EventBus ### What is the Jira issue? * Open an issue on Jira https://issues.apache.org/jira/browse/ZEPPELIN/ZEPPELIN-6340 ### How should this be tested? - Run the existing test suite against the updated code - Verify the note deletion flow through the UI ### Screenshots (if appropriate) ### Questions: * Does the license files need to update?
