[Feature Request] Add support for version-id in S3 backups.

[mrlindblom]

S3 buckets with versioning need a new field called version-id to be able to restore from a older version of the file. Today the backup operator will not see the backup file if for example it been deleted from the S3. However a older version exists and can be access if version-id is specified.

If S3 object lock enable on the bucket, versioning is enabled by default. Use case for S3 object lock is to make sure that no one can tamper or delete backup, for example during a ransomware attack. There has been cases where the bad guys and tired to destroy backup however with S3 Object lock enable this would not be possible.
