test(NODE-4316): sync latest cmap tests for pool pausing

[dariakp]

Description

NODE-4316
fully covers NODE-3254, NODE-3257, NODE-3259
as well as the test sync changes needed for NODE-3255 and NODE-2994

What is changing?

• cmap spec tests are synced with latest
• new pool pause tests are added and skipped
• existing tests have ready operation added (currently no-op)
• one existing test has backgroundThreadIntervalMS option added, the runner types were updated with this new option and the runner itself was updated to check pool options against the known list of options
• another test had a ConnectionPoolReady event added to its list of expected events, which we cannot handle until pool pausing is implemented, so temporary logic was added to filter it out from the expected event list

Note to reviewers:

• verify that existing cmap tests run and pass as before on all configurations of interest (i.e., server, rs, sharded, and lb) and the newly added tests appear in the logs with the expected skip reason
• implementation of handling for appName and timeout in waitForEvent test options is intentionally deferred to NODE-2994 since no running tests currently use them

Is there new documentation needed for these changes?

No

What is the motivation for this change?

Have tests readily available for the core work of pool pausing
