Support to Middlewares

[fefas]

Support to middlewares that can be used not only by Bauhaus but also by users to define common logic to the entrypoints:

class MyCliMiddleware implements CliMiddleware
{
    public function execute(CliInput $input,CliOutput $output, Handler $next): void
    {
        $output->write("foobar");
        $next->execute($input, $output);
    }
}

$settings = CliApplicationSettings::default()
    ->withMiddlewares(
        new MyCliMiddleware(),
        // ...
    );
