Ensure compatibility with MongoDB Driver 5.x

[christophstrobl]

The MongoDB 5.x driver will come with a couple of API changes mainly removing already deprecated API.

The following changes cause compile changes in current main development line and should be resoslved.

• MongoClientSettings#getStreamFactoryFactory() is removed and needs to be checked via getTransportSettings().
• MapReduceIterable no longer supports sharded
• ServerAddress no longer offers the method to obtain an InetSocketAddress. We should make use of the available getHost and getPort methods.

Ideally we can resolve the issues in a way that allows to back port the changes to the 4.2.x branch, providing users with a seamless upgrade experience if they choose to use the 5.x driver along data 4.2 generation.
