[DoctrineMongoDBBundle] BC-break: This removes the excess "connections" and "document_managers" wrapper in XML. This was inconsistent and made normalization unnecesarily difficult.

Previously:

    <connections>
        <connection ...>
            <!-- .. -->
        </connection>
        <connection ...>
            <!-- .. -->
        </connection>
    </connections>

Now:

    <connection ...>
        <!-- .. -->
    </connection>
    <connection ...>
        <!-- .. -->
    </connection>

I believe this is more semantically correct, and it removes code that had to worry about this extra format and normalize it.
