The seven S3-compatible warm backend providers (Aliyun, Azure, Huaweicloud, Tencent, MinIO, R2, RustFS) each carry a byte-identical copy of the same statically-credentialed TransitionClient construction and of the same optimal_part_size helper. Add both to the module that already owns the WarmBackend trait and WarmBackendS3, so the per-provider migrate step can drop its duplicate without redesigning anything. bucket_lookup is a parameter rather than a constant because the providers split into two families: Aliyun, Azure, Huaweicloud, and Tencent pin BucketLookupDNS, while MinIO, R2, and RustFS leave it at the BucketLookupAuto default. Hardcoding either value would silently change bucket addressing for the other family during the migrate step. Error texts, validation order, prefix and host/port normalization are reproduced exactly from the Aliyun/MinIO family. No provider file is touched and no production caller exists yet, so the new unit tests are the first callers. Refs rustfs/backlog#2040
