S3A copyFile operation to include source versionID or etag in the copy request

      Description

      The S3 CopyObjectRequest structure used to build a copy request takes, optionally

      • a version ID of the source file
      • the etag of the source file

      using these will guarantee that the source file is copied exactly once

      1. When working with S3Guard in auth mode, and the etag/version are kept in the DDB table, that should be the authoritative source of metadata: fail fast if the file is out of date
      2. And when non-auth mode is used, the getObjectMetadata check made should update the s3guard table if needed.
