 Description   

SERVER-32756 introduced a new IndexDescriptor::IndexVersion, kV2Unique, to enable creation of new format unique index in MongoDB 4.0. The index format change which does not involve any semantic change should be dependent on WiredTiger specific index data format version instead.

This ticket tracks the work required to make the new unique index creation dependent on WT specific index data format version instead of IndexDescriptor::IndexVersion.
