memory consumption of AssociationKey
------------------------------------

                 Key: OGM-150
                 URL: https://hibernate.onjira.com/browse/OGM-150
             Project: Hibernate OGM
          Issue Type: Improvement
            Reporter: Sanne Grinovero


Each AssociationKey is containing several fields which are related to the specific Role of the collection, and could be wrapped in a single object reusable for the specific role.

We could avoid exposing this object from the AssociationKey interface, so that the specific Dialect can define custom metadata.

Goals:
 - reuse the object instances
 - make sure that AssociationKey instances, which are potentially as many as the association instances in some configurations (not using custom serialization), have the minimum number of fields defined.
