when migrating to the uuid-based identifiers, the mapping from the integer-based generation to the shard-id is preserved. we used to have "gen % smp_count" for calculating the shard which is responsible to host a given sstable. despite that this is not a documented behavior, this is handy when we try to correlate an sstable to a shard, typically when looking at a performance issue. in this change, a new subcommand is added to expose the connection between the sstable and its "owner" shards.
