docs: Ensure raising of IntegrityError on unique constraint violations.
  
      In earlier versions of hdbcli it doesn't raise the hdbcli.dbapi.IntegrityError
      exception for unique constraint violations. To support also older versions
      of hdbcli this decorator inspects the raised exception and will rewrite the
      exception based on HANA's error code.
