We should have an additional {{setDefaultKryoSerializer}} method that allows
overriding the global default serializer, without the need to specify a class
(out-of-the-box Kryo uses the {{FieldSerializer}} if no matches for default
serializer settings can be found for a class). Internally in Flink's
{{KryoSerializer}}, this would only be a matter of setting that configured
global default serializer for Kryo by calling
{{Kryo.setDefaultSerializer(...)}} on the created Kryo instance.
