`ExtraArgs` arguments supported by `Bucket.copy`

[LeonidVas]

Hi! As far as I understood from https://github.com/boto/s3transfer/blob/279f82c6f9d01b19abf69d8fa08441c2064fba7f/s3transfer/manager.py#L381 the Bucket.copy operation should support ALLOWED_COPY_ARGS set of arguments in ExtraArgs (that is more than ALLOWED_UPLOAD_ARGS), but in the documentation and here describes that Bucket.copy supports only ALLOWED_DOWNLOAD_ARGS.

Which of the options is correct:

• it is a mistake in the documentation and ALLOWED_COPY_ARGS support is guaranteed
• a guaranteed set of arguments - only ALLOWED_DOWNLOAD_ARGS and it is not reasonable to use other arguments
• I missed something when investigating the code and only the ALLOWED_DOWNLOAD_ARGS set of arguments is actually supported

Hi @LeonidVas,

Thanks for bringing this to our attention. This looks like a copy-paste error and the documentation should refer to ALLOWED_COPY_ARGS for the copy command.

What is the status of this issue? According to the commit link for this problem, I assume that this problem is only present in the docs.
