Refactor BaseDataCollector to utilize CollectorStateAndTelemetry for improved state management
- Introduced a new `CollectorStateAndTelemetry` class to encapsulate the status, health checks, and statistics of the data collector, promoting modularity and separation of concerns. - Updated `BaseDataCollector` to replace direct status management with calls to the new telemetry class, enhancing maintainability and readability. - Refactored logging methods to utilize the telemetry class, ensuring consistent logging practices. - Modified the `OKXCollector` to integrate with the new telemetry system for improved status reporting and error handling. - Added comprehensive tests for the `CollectorStateAndTelemetry` class to ensure functionality and reliability. These changes streamline the data collector's architecture, aligning with project standards for maintainability and performance.
