Description

With the checksum_algorithm params set to md5 our S3 provider (Outscale) was still rejecting publish splits requests with the following error 400 BadRequest: "trailing checksum is not supported".
It appears that the AWS SDK was still adding its own crc32 checksum as a trailer on streamed requests.

This fix this behavior by setting RequestChecksumCalculation to WhenRequired rather than WhenSupported (which is the default) for md5/disabled checksum_algorithm option.

How was this PR tested?

Tested on a dev env against the S3 provider to validate ingestion.
