Refactor Ingestor and Manager classes to use CoreNotificationHandler and improve metadata handling
- Updated Ingestor class to initialize logger using get_logger and replaced notification handler initialization with metadata dictionary.
- Refactored DataManager, IngestorManager, OpcManager, and ResourceManager classes to inherit from BaseActivity, allowing for consistent logger and notification handler usage.
- Enhanced notification handling by integrating metadata into notification methods across various managers.
- Added .vscode/ to .gitignore to exclude VSCode configuration files.
