Provide autowiring for Exporter class

Feature Request

Provide autowiring for sonata.exporter.exporter class

Cannot autowire argument $exporter of "AppBundle\Controller\LogController::exportAction()": it references class "Exporter\Exporter" but no such service exists. You should maybe alias this class to the existing "sonata.exporter.exporter" service.

I actually need to use this workaround inside Kernel.php

$aliases = ([
    \Exporter\Exporter::class => 'sonata.exporter.exporter',
]);

IMO its not a best practice to do that for a third party bundle, but I can be wrong

No need to do it in PHP, you can define an alias in your services.yaml file

See symfony/symfony-docs#9886 not sure if we should do that for no services at all, or allow doing it for services relevant to the end user

Where did you see that? It's done on many bundles. And how will you provide auto-wiring without this method?

The only better thing to do here is to provide an interface.

@OskarStark please see https://github.com/symfony/symfony-docs/blob/master/bundles/best_practices.rst#services, apparently the best practice is exactly what is proposed here.
