 * Ensure that the `stepzen-config.yaml` file exists and has valid content.

 *      -> initialize the config file and add a UUID into it
 *  - file exists but does not include a UUID (it was created by an earlier
 *    version of the CLI)
 *       -> add a UUID into the existing config file
 *  - file exists, has stepzen credentials, but does not include an API key
 *    (it was created by an earlier version of the CLI)
 *       -> either fetch the API key from StepZen or remove logged in credentials
 *
 * @param {*} maybeConfiguration raw contents of the configuration file
 * @returns machine configuration along with a flag telling whether or not it
 *          was modified
