Research direction

Read the counterpart pull request at https://github.com/dask/gcsfs/pull/20 and the S3 consistency notes in the issue. Identify the existing S3 upload and metadata-checking entry points before determining how the ETag rules apply to simple and multipart uploads. Done means the intended consistency check is implemented and its behavior is covered by tests.
