This PR improves the robustness of object storage operations by retrying both explicit throttling errors (e.g. HTTP 429, SlowDown, ServerBusy). These errors commonly occur under high concurrency and are typically recoverable with bounded retries. issue: https://github.com/milvus-io/milvus/issues/44772 <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Configurable retry support for reads from object storage and improved mapping of transient/rate-limit errors. * Added a retryable reader wrapper used by CSV/JSON/Parquet/Numpy import paths. * **Configuration** * New parameter to control storage read retry attempts. * **Tests** * Expanded unit tests covering error mapping and retry behaviors across storage backends. * Standardized mock readers and test initialization to simplify test setups. <sub>✏️ Tip: You can customize this high-level summary in your review settings.</sub> <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Signed-off-by: bigsheeper <yihao.dai@zilliz.com>
