Description

We currently register a bunch of serializers with Kryo without specifying registration IDs. As a result we are locked in to a specific number of serializers.

In order to allow the KryoSerializer to be used without the Scala serializers being registered, we need to pin the registration IDs of our current java serializers. This also includes user-defined serializers in the execution config.
