Upload retry support (to mirror download retry behavior)

[lsowen]

S3Transfer (and thus boto3) has the num_download_attempts, which handles retries for issues like socket.timeout, socket.error, etc.

It would be greatly helpful if a similar option as added (and exposed up through boto3) for the upload direct.

Marking as a feature request.

Is this implemented?
What is the default no of retry attempts internally for upload?

This would be particularly helpful for multipart uploads, where one chunk might fail towards the end of a potentially very large upload. With the current behavior, the transfer aborts and the entire file has to be reuploaded. Ideally, the library would retry the failed chunk(s) and proceed with other chunks until it hit a failure threshold for any given chunk.
