Public bug reported:

Long time ago a todo was made in placement:
https://github.com/openstack/nova/blob/faede889d3620f8ff0131a7a4c6b9c1bc844cd06/nova/objects/resource_provider.py#L1837-L1839

We need to implement that TODO, this is a note to self.

This is related to what may be a different bug: when heavily loaded with
many single requests, the placement server is unexpectedly receiving
409's about generation problems. Discussion of that led to remembering
that this TODO needs to be fixed. Fixing the TODO needs to be done
regardless of that problem.

** Affects: nova
     Importance: Medium
         Status: Triaged


** Tags: note-to-self placement
