What's Changed

Common to both Azure API for FHIR and Azure Health Data Services

• [Bundle] Handling cancellation in case of throttling by @fhibf in https://github.com/microsoft/fhir-server/pull/5577: When a bundle request was throttled (HTTP 429) and the client cancelled the request during the retry wait, the server could exhibit unexpected behavior. The server now properly handles cancellation during retry delays and returns HTTP 408 (Request Timeout) for affected bundle entries. The maximum retry-after delay is also capped at 15 seconds.
