Add command line parsing and configuration management

* Introduced `CommandLine` class for handling command line options and arguments
* Added `TestConfiguration` class to manage application credentials and URIs
* Implemented example usage for generating command line arguments from a configuration object
* Updated `package.json` to include `commander` dependency
* Removed unused `TestRunner` class and created a new `TestRunner` for executing tests with command line options
* Adjusted logging level type to use lowercase values for consistency
