MongoDB Client Extension - NullPointerException in native mode with ChangeStreamDocumentCodec

[JiriOndrusek]

Describe the bug

MongoDb client does not contain registration for reflection of ChangeStreamDocument. Therefore it causes NPE in https://github.com/mongodb/mongo-java-driver/blob/master/driver-core/src/main/com/mongodb/client/model/changestream/ChangeStreamDocumentCodec.java#L44

To Reproduce

You can use camel-quarkus and its test. Following change has to be present - apache/camel-quarkus#2642
Then you have to:

1. Remove workaround of this issue, be removing method MongoDbProcessor.reflectiveClass (https://github.com/apache/camel-quarkus/pull/2642/files#diff-a69e11de2fa675737)
2. Run tests from module integration-tests/mongodb in native mode. You can use command mvn clean verify -Pnative -f integration-tests/mongodb
   Following exception should happen:
