the subcommand of "shard-of" does not support tablets yet. so let's print out an error message, instead of printing the mapping assuming that the sstables are distributed based on token only. this commit also adds two more command line options to this subcommand, so that user is required to specify either "--vnodes" or "--tablets" to instruct the tool how the cluster distributes the tokens across nodes and their shards. this helps to minimize the suprise of user. this change prepares for the succeeding changes to implement the tablets support. the corresponding test is updated accordingly so that it only exercises the "shard-of" subcommand without tablets. we will test it with tablets enabled in a succeeding change.

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.
