[Serialization] Hazelcast extension : using HazelcastSedaProducer with transferExchange=true

On native mode, it's impossible use to write HazelcastSedaProducer with transferExchange=true.
The reason is there an issue while writing object of type [DefaultExchangeHolder](https://github.com/apache/camel/blob/master/core/camel-support/src/main/java/org/apache/camel/support/DefaultExchangeHolder.java). It's related to this issue [graal#460](https://github.com/oracle/graal/issues/460)

Also for integration tests for HazelcastAggregationRepository and ReplicatedHazelcastAggregationRepository, that use the same Serializable class object.
