The path for the config is obsolete for Symfony 4

[gabiudrescu]

On Symfony Flex, when trying to get /admin without any entity configured renders the error below:

The "BlogPost" entity is not defined in the configuration of your backend. Solution: edit your configuration file (e.g. "app/config/config.yml") and add the "BlogPost" entity to the list of entities managed by EasyAdmin.

But the config for EasyAdmin is in another file: config/packages/easy_admin.yaml. the old one (app/config/config.yml) is obsolete

I'm closing this issue because we're starting a new phase in the history of this bundle (see #2059). We've moved it into a new GitHub organization and we need to start from scratch: no past issues, no pending pull requests, etc.

I understand if you are angry or disappointed by this, but we really need to "reset" everything in order to reignite the development of this bundle.
