Public bug reported:

The detailed response from the nova usage call, reports invalid instance
size info if the instance has been resized.  This API is used by
Horizon, which is how we found this.

Steps to reproduce:

1)  Create an instance, say small

2) resize the instance, something like large etc

3) Make this call (adjust to hit a recent date etc):
nova --debug usage --start 2015-12-01 --tenant XYZ

Doing that call, we see the VCPU count reflect the old size for the
instance.   This makes horizon quota and usage calculations display the
wrong info, and prevents users from getting work done.
