In a concurrency fsm workload test, the workload itself sets up a collection and provides it to the test to use. In the case of sharded concurrency suites, the test setup may also shard the collection. However, some of these tests cannot use the provided collection because they require a collection with certain non-default options. Thus, they manually create a collection themselves as a part of the test-defined setup. One prominent case of this is time-series collections. In these cases, this causes the collection used by the test to not actually be sharded. We should make it so that test-defined collections get sharded as well, so that we get proper test coverage.
