> Various objects stores provide etags in their FileStatus implementations

> * 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

> etags of uploaded files, so diff properly.
