Currently, the change stream prose tests are only partially implemented.

*Acceptance Criteria:

• Implement tests 1-4, 5-9
  • Note: #3 has a partial implementation in change_stream.test.js > Change Stream Resume Error Tests)
  • Note: #9 requires >=4.0 and <4.0.7 which is not what we have in the pipeline, so perhaps that test can be removed from the spec - confer with drivers group
• Fix tests 11-14 to run against a real server instead of a mock, if possible
• Review tests 17-18 and make sure implementation matches spec
• Make sure all tests run against both replicaset and sharded cluster unless otherwise specified in spec (currently only run against replicaset)
• Update describe/it blocks to accurately convey spec test title (for easy discovery)
