s3: fix --header-upload - Fixes #4303

Browse Source 
Before this change we were setting the headers on the PUT
request for normal and multipart uploads. For normal uploads this caused the error

    403 Forbidden: There were headers present in the request which were not signed

After this fix we set the headers in the object upload request itself
as the s3 SDK expects.

This means that we only support a limited range of headers

- Cache-Control
- Content-Disposition
- Content-Encoding
- Content-Language
- Content-Type
- X-Amz-Tagging
- X-Amz-Meta-

Note for the last of those are for setting custom metadata in the form
"X-Amz-Meta-Key: value".

This now works for multipart uploads and single part uploads
