Piotr Sarna 09e4f3b917 alternator: implement ScanIndexForward ...

The ScanIndexForward parameter is now fully implemented
and can accept ScanIndexForward=false in order to query
the partitions in reverse clustering order.
Note that reading partition slices in reverse order is less
efficient than forward scans and may put a strain on memory
usage, especially for large partitions, since the whole partition
is currently fetched in order to be reversed.

Fixes #5153
