When in tablets_mode_for_new_keyspaces=enforced mode, Alternator is supposed to fail when CreateTable asks explicitly for vnodes. Before this patch, this error was an ugly "Internal Server Error" (an exception thrown from deep inside the implementation), this patch checks for this case in the right place, to generate a proper ValidationException with a proper error message. We also enable the test test_tablets_tag_vs_config which should have caught this error, but didn't because it was marked xfail because tablets_mode_for_new_keyspaces had not been live-updatable. Now that it is, we can enable the test. I also improved the test to be slightly faster (no need to change the configuration so many times) and also check the ordinary case - where the schema doesn't choose neither vnodes nor tablets explicitly and we should just use the default.

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.
