   * Add an entity as a synonym into another entity.
   *
   * Basically this method should be called when you want to add some entity as
   * a synonym to another entity (for example when you merge one entity into
   * another and besides merging want to add synonym of the merged entity into
   * the trunk entity). You should update $trunk_entity in such a way that it
   * holds $synonym_entity as a synonym (it all depends on how data is stored in
   * your behavior implementation, but probably you will store entity label or
   * its ID as you cannot literally store an entity inside of another entity).
   * If entity of type $synonym_entity_type cannot be converted into a format
   * expected by your behavior implementation, just do nothing.
   *
   * @param object $trunk_entity
   *   Entity into which another one should be added as synonym
   * @param object $synonym_entity
   *   Fully loaded entity object which has to be added as synonym
   * @param string $synonym_entity_type
   *   Entity type of $synonym_entity
