Research direction

Start in lib/backup/cloud_io/s3.rb at lines 205-219, then review the linked fog/S3 metadata example. Define how callers provide arbitrary x-amz-meta-* fields and ensure pushed objects retain them, including a custom MD5 value for multipart uploads. Confirm the behavior against the S3 upload path.

Written by the indexing model from the issue text.

Description

Adding ability to add x-amz-meta-* headers here would seemingly allow us to upload custom metadata fields with our backup, like so:
https://stackoverflow.com/questions/12290819/how-to-upload-s3-metadata-with-a-file-in-fog

This would allow users to get around the fact that S3 doesn't yet allow a means to check the MD5 of the full file when it has been uploaded via multipart. It would allow us to set out own custom metadata with the md5 hash, that we could use ensure S3 files aren't redownloaded if unchanged from expected hash.
