Automatically load routes in app controllers

[aschempp]

If you have controllers with Symfony routes, you currently need to manually add a routes.yaml to your project to load that folder. This would automatically load controller routes if no routes.yaml exists. Loading both is problematic because they could override each other.

We should also automatically add the controller.service_arguments tag for src/Controller services, should we not? Otherwise you cannot use DI in your controllers.

I don't think that's related, that's a configuration of your service. I would usually use #[AsController] which is autoconfigured since we have service autoconfiguration as well.

that's a configuration of your service.

But the point of this PR is to automatically have route configuration available via annotations available for your controllers in src/Controller without having to define a routes.yaml. Just like the services.php automatically registers all classes in App\ as services for you without having to define a services.yaml.

But yes, you can of course add #[AsController] to every controller where you need DI. But since this is about convenience I thought we should also add this to the service configuration as well.

I don't see that as the same thing. This is route registration. The other thing is "make this class public and allow action injection". You can use one without the other, and you don't need add config files now in either way.
