The write_conflicts_with_non_txns.js tries to run that an insert times out via maxTimeMS, but currently maxTimeMS is not propagated from a mongoS to a shard which makes this check unreliable. We should blacklist this test from sharded passthrough suites until maxTimeMS works as expected in this scenario. We have lots of transactions test coverage in sharded clusters so I don't think blacklisting temporarily is a problem.
