Update MongoDB connection handling in DataManager and enhance IngestorManager configuration

- Updated DataManager to simplify MongoDB connection logic by removing retry loop and adding logging for connection attempts.
- Enhanced IngestorManager to accept MongoDB connection parameters and export_to_kafka flag as part of its initialization.
- Updated requirements.txt to use the latest version of the sientia-dataops-library.
