[HttpKernel] Change Resolving the Controller in the Symfony Framework

[wouterj]

While the documented way is still supported, I think we should instead talk about the default way in Symfony 4 (using ContainerControllerResolver and controllers as services).

Thank you for this issue.
There has not been a lot of activity here for a while. Has this been resolved?

Friendly reminder that this issue exists. If I don't hear anything I'll close this.

Closing as it's about an internal component feature.
