Rescheduling uses the RequestSpec, which contains a copy of the Flavor
from the last resize or when the server was initially created. The
RequestSpec is around for the lifetime of the instance, so you can
delete the original flavor and still reschedule.
Now if you created a server or resized a server with a given flavor, and
then modified that flavors extra_specs, that won't be reflected back in
the persisted RequestSpec, but it's probably not a great idea in general
to modify extra_specs on public flavors which are already being used.
