* Support the NOVALUES option of HSCAN

Issue #2705

The NOVALUES option instructs HSCAN to only return keys, without their
values. This is materialized as a new command, `hScanNoValues`, given
that the return type is different from the usual return type of `hScan`.
Also a new iterator is provided, `hScanNoValuesIterator`, for the same
reason.

* skip hscan novalues test if redis < 7.4

* Also don't test hscan no values iterator < 7.4
