YQ Connector: prepare code base for S3 integration

1. Кодовая база Коннектора переписана с помощью Go дженериков так, чтобы добавление нового источника данных (в частности S3 + csv) максимально переиспользовало имеющийся код (чтобы сохранялась логика нарезания на блоки данных, учёт трафика и пр.)
2. API Connector расширено для работы с S3, но ещё пока не протестировано.
