- Updated `README.md` to provide a comprehensive overview of the OPC Ingestor, including features, architecture, installation, usage, and troubleshooting.
- Enhanced docstrings across various classes and methods in the `ingestor` module for better clarity and maintainability.
- Improved Prometheus metrics documentation in `metrics.py` to ensure proper monitoring and observability of the system.
Refactor Ingestor and OPC Manager for Asynchronous Operations
- Updated main function to be asynchronous and integrated asyncio for better concurrency.
- Refactored Ingestor methods to support async operations, including prepare_ingestor, loop, and shutdown.
- Enhanced IngestorManager and OpcManager with async methods for improved performance and responsiveness.
- Replaced blocking calls with await statements to ensure non-blocking behavior during operations.
- Added a new run_async_main function to handle the async event loop setup.
Update requirements and environment configurations
- Changed the sientia-dataops-library dependency to a relative path in requirements.txt.
- Updated image tag to 0.3.0 in values.yaml.
- Renamed HTTP_SERVER_PORT to HTTP_METRICS_PORT in app.py and updated its default value to 9090.
- Added TAG_WRITTEN_COUNT metric in metrics.py to track writing processes.
- Incremented TAG_WRITTEN_COUNT in DataManager upon successful data insertion.
Refactor logging statements in Ingestor and app modules to use f-strings for improved readability and consistency. Updated error and info logs to enhance clarity in the Ingestor class.
Update ingestor and data manager for improved shutdown handling and logging
- Incremented project version in quality gate configuration.
- Commented out ingestor service in docker-compose for clarity.
- Enhanced main loop in app.py to handle exit signals and exceptions.

- Updated unit tests to validate shutdown behavior and exception handling.
- Introduced coverage configuration to omit specific files.
Refactor OpcManager initialization and unsubscribe method; enhance logging
- Removed the `initialize_from_config` method from `OpcManager` class and adjusted the constructor to handle configuration directly.
- Improved the `unsubscribe` method to include detailed logging for non-existent subscriptions.
- Updated tests in `test_opc_manager.py` to reflect changes in the `OpcManager` class.
- Commented out Docker-related fixtures in `conftest.py` for potential future use.
- Enhanced test coverage in `test_single_node.py` and `test_data_manager.py` with additional scenarios and assertions.
- Introduced new methods in `Ingestor` and `IngestorManager` classes to manage server subscriptions and leases more effectively.
