[charley04310]

Description:

This pull request implements the first version of the command-line interface (CLI) for our application using the clap library and loading configuration from a YAML file. This initial implementation will enable our application to act as an HTTP client with the external API.

The CLI implements the following subcommands:

• configure: configure the application with the specified parameters in the YAML configuration file.
• status: display the current status of YAML file.
• apply: apply the current configuration to the external API.
• kill: stop the application.

You can try by using this command :

cargo run -- configure --config-path=<folder-path>/cloudlet/src/cli/config/config.template.yaml
