If you allocate all the memory of a box to high-mem instances, you may
not be billing for all the CPU and disk which are now unusable. That's
why flavors were introduced, afaik, and it's still a valid need.

I totally agree the scheduler doesn't have to know anything about
flavors though. We should push them out to request validation in the
Nova API. This can be considered part of cleaning up the scheduler API.
