Public bug reported:

In https://blueprints.launchpad.net/nova/+spec/cells-count-resources-to-check-quota-in-api we
changed to use new quota check workflows which counts all consumed resources across cells and
comparing with the limits.

But the resources in build_requests was not counted and this might
lead to creating 20 instances in concurrent requests, i'll probably get 10 in ERROR state rather
than 10 plus 10 failed requests with 409s. Which might be a big change to users.

We should also count instance records from build requests as consumed resources in order to
avoid allowing creation requests pass API layer checks and stopped in conductor layer check,
which lead instances to ERROR state.
