…tling Azure Service Bus throttles management operations (GetQueuesRuntimeProperties) used to read queue lengths. The SDK retries the HTTP 429 responses internally, so the throttling never surfaced as an exception and was invisible in the logs while still showing on the namespace dashboard. Observe the 429 responses via a PerRetry pipeline policy on the management client, log a warning once per throttling episode, and reactively back off the query interval (exponential up to 1 min, recovering gradually) until throttling clears. The ServiceBusException(ServiceBusy) catch remains as a fallback for the retries-exhausted case.

Detects Azure Service Bus management throttling via a PerRetry HTTP pipeline policy (observes the 429s the SDK retries away) and reactively backs off the queue-length query interval, logging a warning once per throttling episode.
One of two alternative approaches for the same issue; the other (#5605) disables the SDK retries instead.
