The special SYMFONY__ environment variables have been deprecated in Symfony 3.3 (and will be removed in 4.0) as there is now support for runtime environment variables in Symfony. This commit allows for different environment variables to be used as the first step in removing the old variables. A later step should remove the `parameters.yml` file entirely and have the configuration be solely from passed environment variables (or .env file for development). ref: [Deprecation blog post](https://symfony.com/blog/new-in-symfony-3-3-deprecated-the-special-symfony-environment-variables) ref: symfony/symfony#21889
