// MakeApp creates a cli application (based on `github.com/urlfave/cli` package).
// The application exits when `action` returns.
// Parameters:
// * action: the main function for the application. receives `*cli.Context` with parsed command-line flags. Returns no error, if some error could not be recovered from write to the log or panic.
// * cliFlags: the list of flags `cli.Flag` that the app should set and parse. By default, use `DefaultFlags()`. If you want to specify your own flag, use `append(DefaultFlags(), myFlag)` for this parameter.
