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.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
