Kaloyan Raev 75257fc9cd s3: Storj provider: fix server-side copy of files bigger than 5GB 
Like some other S3-compatible providers, Storj does not currently
implements UploadPartCopy and returns NotImplemented errors for
multi-part server side copies.

This patch works around the problem by raising --s3-copy-cutoff for
Storj to the maximum. This means that rclone will never use
multi-part copies for files in Storj. This includes files larger than
5GB which (according to AWS documentation) must be copied with
multi-part copy. This works fine for Storj.

See https://github.com/storj/roadmap/issues/40

When uploading files larger than upload_cutoff or files with unknown

using this chunk size.
Note that "--s3-upload-concurrency" chunks of this size are buffered
in memory per transfer.
If you are transferring large files over high-speed links and you have
enough memory, then increasing this will speed up the transfers.
Rclone will automatically increase the chunk size when uploading a
large file of known size to stay below the 10,000 chunks limit.
Files of unknown size are uploaded with the configured
chunk_size. Since the default chunk size is 5 MiB and there can be at
most 10,000 chunks, this means that by default the maximum size of
a file you can stream upload is 48 GiB. If you wish to stream upload
larger files then you will need to increase chunk_size.
Increasing the chunk size decreases the accuracy of the progress
statistics displayed with "-P" flag. Rclone treats chunk as sent when
it's buffered by the AWS SDK, when in fact it may still be uploading.
A bigger chunk size means a bigger AWS SDK buffer and progress
reporting more deviating from the truth.
