Morgana future/fix/configuration parsing error mmap log buffer size

[MorganaFuture]

What This PR introduces a JSON-based configuration system for the Tempesta FW logger daemon with:

• A dedicated TfwLoggerConfig class for logger settings
• JSON configuration file support via Boost's property_tree
• Two operation modes: daemon (background) and handle (foreground for debugging)
• Support for a logger_config attribute in the access_log directive
• Updates to Tempesta scripts for compatibility
• Backward compatibility with existing configuration
• Add tests

Why The Tempesta logger configuration is currently scattered across multiple parameters, making it hard to manage. A dedicated JSON file provides a cleaner approach that separates logger settings from the main configuration. This structured format improves error handling and simplifies troubleshooting with the new foreground mode.
