- Add syntax to aggregate command to allow QueryPlannerParams::TRACK_LATEST_OPLOG_TS to be set. Some care must be taken to reject user requests which attempt to set the parameter for a non-oplog namespace.
- Add Timestamp latestOplogTimestamp to the CursorResponse type.
- CursorResponseBuilder::setLatestOplogTimestamp() should likely be called in all the same places CursorResponseBuilder::setPostBatchResumeToken() is being called today.
- If latestOplogTimestamp.isNull() then omit the field from the cursor command response.
