Мне нужно добавить определение нового изменения:
В запросе объекта insurant пришли данные lastName, name,middleName,
dateOfBirth и identityDocument.
Для определения произошла ли смена страхователя или корректировка
данных существующего необходимо сравнивать ФИО, ДР и Паспртные
данные.
Если было определено измененние более 2х символов в хотя бы из одном
полей ФИО и ДР, а также изменение паспортных данных, то считаем, что
произошла смена участника договора.

Ограничение:
Проверка, что новый страхователь не является собственником. Сравнить по ФИО+дате рождения. Необходимо проверять ФИО + ДР на нахождение в черном списке при изменении данных ФИО и ДР
