> Various objects stores provide etags in their FileStatus implementations
> Make these values accessible
> * new interface {{EtagFromFileStatus}} to be implemented when provided
> * filesystem.md to declare requirements of etags (constant between LIST and
> HEAD)...
> * path capabilities for (a) etag and (b) etags consistent across rename
> Add implementation for abfs, later s3a (and google gcs)
> This is initially to handle recovery from certain failures in job commit
> against abfs, but it would allow a cloud-ready version of distcp to track
> etags of uploaded files, so diff properly.
