Botond Dénes f15551d23a query: partition_slice: add range_scan_data_variant option ...

Switching to the data variant of range scans have to be coordinated by
the coordinator to avoid replicas noticing the availability of the
respective feature in different time, resulting in some using the
mutation variant, some using the data variant.
So the plan is that it will be the coordinator's job to check the
cluster feature and set the option in the partition slice which will
tell the replicas to use the data variant for the query.
