Public bug reported:

With the refactoring work moving PCI requests from system_metadata to
instance_extra, PCI requests are no longer accessible from the instance
object. Refer to https://review.openstack.org/#/c/118391/. One of the
issues is that the scheduler while consuming PCI requests (see
consume_from_instance in host_manager.py) needs access to db to get the
PCI requests. Another issue is that the compute node would need multiple
DB accesses to get the PCI requests, while if they are part of the
instances, they can become available together with the instance.
