add ?orphan-relations=1 query param to api that deduplicates api responses. add ?exclude-relations=relation_name1,relation_name2 query param to api that drops named relationships from api responses. add ?include-relations=relation_name1,relation_name2 query param to api that only includes namded relationships in api responses. These add up to significant response time and respons size improvements.
fix typo and add missing line from downstream diff to preloaded_object_serializer for orphaning relations
add unit tests for ?orphan-relations, ?exclude-relations and ?include-relations query params
Refactor preloaded_object_serializer to reduce complexity. Add additional tests to paginated_object_renderer for orphan-relations, exclude-relations and include-relations query param handling. Move exclude-relations and include-relations query param parsing to common_params.
Merge remote-tracking branch 'origin/pr/300'
