Public bug reported:

On resizes, the RequestSpec object sent to the scheduler contains the
instance's original flavor.  This is causing an issue in our scheduler
because it is not seeing a new flavor for the resize tasking.

The issue appears to be that at
https://github.com/openstack/nova/blob/76dfb4ba9fa0fed1350021591956c4e8143b1ce9/nova/conductor/tasks/migrate.py#L52
the RequestSpec is hydrated with self.instance.flavor than the new
flavor which is  self.flavor.
