  - s3: Optimize WRITE_CHUNKSIZE to minimize an overhead
    
    When processing the image data from a client, the previous and small
    chunk size had a significant overhead. Let's be aligned with other chunk
    size related parameters such as DEFAULT_LARGE_OBJECT_MIN_CHUNK_SIZE
    (=5MiB) and DEFAULT_LARGE_OBJECT_CHUNK_SIZE (=10MiB).
    
    The performance difference should be tangible especially with a
    singlepart upload. And the upload time can be shortened for example as
    follows:
    
    100 MiB:   36.5s -> 4.0s
    200 MiB: 2m16.8s -> 6.1s
    300 MiB: 4m50.4s -> 9.1s
