[Bug 1858787] [NEW] nova-scheduler does not use image_metadata when resizing instances
Public bug reported:
Description
===========
We found that nova-scheduler does not use image_metadata when resizing instances.
Steps to reproduce
==================
We have several type of hosts using aggregate.
TypeA:
- aggregate metadata
- image_host_type=A
TypeB:
- aggregate metadata
- image_host_type=B
And we set image_metadata to use aggregation host.

Looks good when creating VM.
But, does not work when resizing VM.
