Creates a new command-line interface for managing Edge Connect applications and instances with the following features: - Configuration management via YAML files and environment variables - Application lifecycle commands (create, show, list, delete) - Instance management with cloudlet support - Improved error handling and authentication flow - Comprehensive documentation with usage examples The CLI provides a user-friendly interface for managing Edge Connect resources while following best practices for command-line tool development using Cobra and Viper.
