Bug Description

The large pages of source compute node should be hold for a possible revert to the old instance type before resize-confirm, but it don't work because 'hw:mem_page_size' in flavor wasn't stashed in instance system metadata, so resource tracker didn't update the usage of large pages for resize/migration instance.

See details:
ResourceTracker._update_usage_from_migration
flavors.extract_flavor
flavors.save_flavor_info
