      Summary of necessary driver changes

      • Remove all token bucket code.
      • Remove the adaptiveRetries client knob and URI option.
      • Add two new client knobs/URI options: maxAdaptiveRetries and enableOverloadRetargeting.
      • Full details in #1b15cd2 (see client-backpressure and uri-options changes)
      • Drivers should include the following release note: "Added support for MongoDB 's Intelligent Workload Management (IWM) and ingress connection rate limiting features. The driver now gracefully handles write-blocking scenarios and optimizes connection establishment during high-load conditions to maintain application availability," with a link to IWM page in Atlas, which which will be available with DOCSP-55426 & related Driver Docs, which will be available with DOCSP-57078.
      • Drivers should also ensure that the two new client options are documented in their official connection option docs.

      Commits for syncing spec/prose tests
      (and/or refer to an existing language POC if needed)

      • #1b15cd2: There are both new tests added and existing tests updated.

      1. What would you like to communicate to the user about this feature?

      There are two new URI options: `maxAdaptiveRetries` and `enableOverloadRetargeting`. These are documented here.

      The `adaptiveRetries` URI option added in CDRIVER-6092 is no longer present.

      2. Would you like the user to see examples of the syntax and/or executable code and its output?

      Not necessary.

      3. Which versions of the driver/connector does this apply to?

      2.3.0+
