Implement enhanced data collection system with health monitoring and management

- Introduced `BaseDataCollector` and `CollectorManager` classes for standardized data collection and centralized management.
- Added health monitoring features, including auto-restart capabilities and detailed status reporting for collectors.
- Updated `env.template` to include new logging and health check configurations.
- Enhanced documentation in `docs/data_collectors.md` to provide comprehensive guidance on the new data collection system.
- Added unit tests for `BaseDataCollector` and `CollectorManager` to ensure reliability and functionality.
