Addition of new index format allows use of both V2 and V2Unique format. Initially we would add a gating variable to select the unique index format. Switch to FCV as the deciding factor for which format should be used.

Setting FCV=4.2 will cause all unique indexes to be updated to V2Unique. Do not update the content of the indexes.
Having FCV=4.0 would create older V2 format indexes
