* Exec a command and get the output. * Output will be streamed to the live console. * Returns promise with the exit code and collected stdout and stderr * * @param commandLine command to execute (can include additional args). Must be correctly escaped. * @param args

(commandLine, args, options)

 * @returns   Promise<ExecOutput>   exit code, stdout, and stderr
