    collection_backend_child_added: Inherit OAuth 2.0 support.
    
    Collection children will inherit the collection source's EOAuth2Support
    object if set.  That way OAuth 2.0 availability is consistent across the
    entire collection, even if it's not USED by all sources in the collection.
