DRIVERS-2578 Drivers use polling SDAM on AWS Lambda #1452

Closed ShaneHarvey closed 1 year ago

ShaneHarvey commented 1 year ago

Changes:

Disable streaming SDAM by default on AWS Lambda and similar FaaS platforms.
Introduce the serverMonitoringMode=stream/poll/auto URI option.
Add Unified Test Format version 1.17 to add support for server heartbeat events and asserting on the "awaited" field.
Clients MUST NOT use dedicated connections to measure RTT when using the polling protocol.

Checklist:

[X] Update changelog.
[X] Make sure there are generated JSON files from the YAML test files.
[X] Test changes in at least one language driver. Python implementation: https://github.com/mongodb/mongo-python-driver/pull/1360
[X] Test these changes against all server versions and topologies (including standalone, replica set, sharded clusters, and serverless).

I've updated the Unified Test Format to version 1.17 by adding support for listening to SDAM ServerHeartbeat events and asserting on the "awaited" field. This improves the SDAM integration test. Ready for another look.
