[Developers] disk space usage reporting

[David Rideout]

There is some implicit assumption being made here regarding use of
permanent storage, and/or the duration of value of the data.  One can
get wrong ideas about costs without making these assumptions explicit.
 For example, if I do not have access to tape backup, and I want to
keep my data forever, then a 500GB run would cost $500.
