Move trigger_dns_resolver() inside the repeat_until loop instead of calling it once before the loop. The test was intermittently timing out on CI. The exact root cause is not fully understood, but the hypothesis is that a single trigger signal can be lost somewhere (not exactly known where). This is not an issue for the production code because refresh trigger will be called multiple times - in every query where all configured nodes will be unreachable. By triggering inside the loop, we ensure the signal is re-sent on each iteration until the resolver actually performs the refresh and picks up the new (failing) DNS resolution. This makes the test resilient to timing-dependent signal loss without changing production code. Fixes: SCYLLADB-1794

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.
