This PR was merged into the 2.7 branch.Discussion----------Explain sample configuration parameter usageThe "Processing the `$configs` Array" section explains how to define parameters within the Configuration class and process them in the Extension. In my opinion, it doesn't take the example to a logical conclusion. People reading this file want to learn how to create configuration within a Bundle. It would be helpful to explain how the configuration can be used. Since the example uses parameters, I propose showing how the parameters can be loaded into the container. With these code changes, the `twitter.client_id` and `twitter.client_secret` are now available through use throughout the application.Commits-------ceacc7c Explain sample configuration parameter usage
