This PR was squashed before being merged into the 4.3 branch (closes #11803). Discussion ---------- More updates related to Symfony configuration This makes several changes related to config. 1) Now that the TOC is displayed so prominently, it's easy to spot things to improve in the article hierarchy. So, I've made the following changes (left: before, right: after): ![image](https://user-images.githubusercontent.com/73419/59919547-03828980-9428-11e9-8d2f-2890c75b6ae1.png) 2) the multiple ".env" files section has been reworded and now it follows the same structure as the comments of the associated recipe, which I think are better. 3) The main Confgi article now explains the different kinds of params you can define ... so we've deleted the service_container/parameters.rst article which is no longer needed. 4) The main Config article adds a new section to explain how to get config values in services and controllers. With these changes I considered finished the main Config article. Thanks. Commits ------- c7a62b8 More updates related to Symfony configuration
