The test samples sl:default runtime before and after setup writes to prove that it measures the scheduling group used by regular CQL writes. The metric is exported in milliseconds, so a single 200-row batch may not be visible immediately, or may be too small in some environments. Keep the original 200-row table size, but wait up to 30 seconds for the metric to advance. If it does not, retry the same writes before TTL is enabled. The retries update the same keys, so the expiration part of the test still waits for exactly the original number of rows. In a local 100-run with N=200 rows, the observed delta of `ms_statement_before - ms_statement_before_write` was: min=4.0, max=16.0, mean=8.13, and median=8.0. Therefore, it looks possible that in a rare corner case the delta drops even to 0. Fixes SCYLLADB-1869 Closes scylladb/scylladb#29797

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.
