Kom-python-logging

Added
- get_current_version function to read the version number from setup.py.
- get_latest_pypi_version function to fetch the latest version of the package from PyPI.
- compare_versions function to compare the current version with the latest PyPI version.
- main function to orchestrate the version check.
- Test cases for get_current_version, get_latest_pypi_version, compare_versions, and the main execution block.
- Test case using subprocess to ensure the if __name__ == "__main__": main() block is executed and covers the script entry point.

Changed
- Refactored workflow_scripts/check_versions.py to include the main execution logic in the main function for better testability.

Fixed
- Ensured tests do not depend on the actual contents of setup.py by mocking the version number.

Added
- Support for structured logging (JSON-formatted logs) to improve log readability and facilitate log parsing by log management systems like ELK stack or Splunk.
- JSONFormatter class to format log records as JSON.
- json_format parameter in setup_logger function to enable JSON formatting.
- Unit tests to validate JSON formatted logs and ensure they include all required fields.
- Test cases for JSON formatted logs to check for correct fields and content.

Changed
- setup_logger function updated to accept json_format parameter for structured logging.

Added
- Configuration for Black code formatter to align with Flake8 linting styles.
- Black's `pyproject.toml` configuration file with a line length of 79 characters to match Flake8.
- Flake8's `.flake8` configuration file updated to ignore `E203` and `W503` for compatibility with Black.
- Option to enable console logging in addition to file logging in the `setup_logger` function.
- Error handling to ensure at least one logging option (file or console) is enabled.
- Sad path tests to handle invalid log levels, invalid log file paths, and missing parameters.

Changed
- Default line length changed from 88 to 79 characters to maintain consistency with Flake8.
- `setup_logger` function updated to raise an error if both `log_file` and `console` are not provided.
- Updated test cases to include validations for new error handling.

Fixed
- Handled `None` values in `set_logging_level` function to avoid `AttributeError`.
- Corrected the expected exception in the `test_invalid_log_file_permission` test case from `PermissionError` to `FileNotFoundError`.

Added
- `set_logging_level` function to map string level names to logging constants.
- Ability to set logging levels dynamically based on string input (e.g., "DEBUG", "INFO").
- Parametrized tests to verify logging levels and ensure correct behavior for different levels.

Changed
- Updated `setup_logger` function to accept logging level as a parameter.

Added
- Initial setup of the logging package with `setup_logger` function.
- Basic logging configuration with file handler and formatter.
- Unit tests to verify basic logging functionality.
