BC Break : FeedContentProvider replaced with FeedProvider

Compatibility with feed-io 3 and 4

rss-atom-bundle now comes with feed-io 4 if PHP's version is 7.1 or higher. It is still possible to use feed-io 3 by requiring it in composer.json like described here : https://github.com/alexdebril/rss-atom-bundle/blob/master/README.md#going-back-to-feed-io-30

Dependency Injection cleaning

StreamController no longer uses the container to fetch services
debril.provider.default service is renamed into debril.rss_atom.provider. debril.provider.default becomes an alias of debril.rss_atom.provider to protect backward compatibility

Compatibility with Symfony 4

Fix JSON content-type

StreamController always sent a "Content-Type: application/xhtml+xml" header, even if the content was a JSON feed. This is now fixed.
