/**
* This test uses the test only `pinHistoryReplicated` command to exercise DurableHistoryPins
* across rollback.
*
* The `pinHistoryReplicated` command will pin the oldest timestamp at the requested time (with an
* optional rounding up to oldest). If the pin is successfully, the pinned time is written to a
* document inside `mdb_testing.pinned_timestamp`.
*
* For the purposes of this test, the write is timestamped as its replicated in the oplog. If the
* write gets rolled back, this test ensures any pinning effect it had is removed.
*
* @tags: [
* requires_majority_read_concern,
* requires_persistence,
