If a time series collection is tracked as unsplittable, it currently cannot be moved, since movePrimary will ignore it and we haven't enabled the feature flag for resharding a time series collection (SERVER-80690). Our suites with config transitions require the config shard to fully drain, so if a test creates an unsplittable time series collection on the config server, it cannot be moved, and the test will time out. To avoid failures while waiting for SERVER-80690, we should temporarily disable tests that may create an unsplittable time series collection from suites with config shard transitions.
