Advantages avoids 100's of stats which are needed for each upload operation in FS/NAS gateway mode when uploading a large multipart object, dramatically increases performance for multipart uploads by avoiding recursive calls. For other gateway's simplifies the approach since azure, gcs, hdfs gateway's don't capture any specific metadata during upload which needs handler validation for encryption/compression. Erasure coding was already optimized, additionally just avoids small allocations of large data structure. Fixes #7206
