Add Configuration Management System with Azure App Configuration Integration
Description
This PR introduces a flexible configuration management system for Booster applications, supporting multi-tier configuration resolution and external configuration providers. The system enables applications to retrieve configuration values from multiple sources with automatic fallback, allowing for dynamic configuration updates without requiring code changes or redeployments.
The implementation includes seamless integration with Azure App Configuration, automatic infrastructure provisioning, label-based environment isolation, and comprehensive documentation.
