Symfony 4.4 deprecation / Symfony 5.0 compatibility

[teohhanhui]

Not declaring the "Symfony\Bridge\Doctrine\DependencyInjection\AbstractDoctrineExtension::getMetadataDriverClass" method in class "Doctrine\Bundle\MongoDBBundle\DependencyInjection\DoctrineMongoDBExtension" is deprecated since Symfony 4.4. This method will be abstract in Symfony 5.0.

Spotted in api-platform/core#3009

Thanks. I’m wrapping up Symfony compatibility for all the bundles currently. We’ll release a 5.0 release of the bundle in time for Symfony 5.
