test proposal: powertop!

[Bill Nottingham <notting redhat com>]

I'd like us to do regular power testing of Fedora (around milestones,
and occasionally in rawhide) with powertop.

Ideally, we'd:
- have one or two defined hardware platforms
- have a few defined workloads (idle system, idle desktop, desktop
  with some apps running)

and then check them periodically to make sure we're not regressing.

Opinions?
