Enhance Ingestor Class with Asynchronous Metrics and Monitoring Integration

- Refactored Ingestor class to inherit from SientiaMonitoring for improved observability.
- Updated methods to utilize asynchronous operations for declaring active ingestors and managing slots.
- Integrated pod_id label into various metrics for better tracking.
- Adjusted unit tests to reflect changes in the Ingestor initialization and asynchronous behavior.
