In test-mongoc-command-monitoring.c, test_bulk_write runs a bulk operation and then checks to see if the events BSON matches the expected events object in bulkWrite.yml and bulkWrite.json.

In the expected output, we expect a

for both acknowledged and unacknowledged writes. This is only correct when interacting with server versions below 3.6.

Starting in 3.6, we use OP_MSG to handle wc: 0 and should no longer expect a server reply.

We should add a flag in bulkWrite.yml and bulkWrite.json that indicates whether or not we should be using OP_MSG so that we can skip tests accordingly.
