Review Comment:
Hmm.
Not very sure. All other classes related to List parsing were there only so
kept it there.
But again this is used in public interfaces. What do you suggest will be a
good place for this?

> On blob endpoint, there are a couple of handling that is needed to be done on
> client side.
> This involves:
> # Parsing of xml response and converting them to VersionedFileStatus list
> # Removing duplicate entries for non-empty explicit directories coming due
> to presence of the marker files
> # Trigerring Rename recovery on the previously failed rename indicated by
> the presence of pending json file.
> Currently all three are done in a separate iteration over whole list. This is
> to pbring all those things to a common place so that single iteration over
> list reposne can handle all three.
