Ability to choose the mode for Spliterator in YdbRepositoryTransaction.executeScanQuery

[std000]

YdbSpliterator has several issues described here: #42

It would be desirable to have a way to choose the Spliterator mode, similar to how it's implemented in readTable().
Currently, in the method YdbRepositoryTransaction.executeScanQuery, the Spliterator is created unconditionally.

YdbSpliterator<RESULT> spliterator = createSpliterator("scanQuery: " + yql, false);

Good catch!

If you use scan mode to execute ordinary queries, the Spliterator setting (set via TxOptions.scanOptions.useNewSpliterator) is respected. But in streaming mode offered by YdbRepositoryTransaction.executeScanQuery(), the value TxOptions.scanOptions.useNewSpliterator is ignored for some reason 😳

I also cannot set this option because it's taken from a default constant.

return new ScanBuilderImpl(TxOptions.ScanOptions.DEFAULT);

Oh, ScanBuilder has no way of setting ScanOptions.useNewSpliterator, this oversight also needs to be fixed on YOJ side.
