Bug description:
NB: This comes from code inspection, not observed behavior.
When the compute service is deleted, we attempt to delete from
placement the resource provider associated with the compute node
associated with the service [1].
But ironic deployments can have multiple compute nodes. In this case,
the compute node associated with the service is the "first" such node
[2].
What happens then is the compute node records are deleted, leaving the
remaining N-1 nodes' provider records orphaned. Those get cleaned up
(I think?) by update_available_resource when the service is recreated
[3].
So we're deleting and recreating the ironic node resource providers,
but in a weird order. We should probably either fix the code at [1] to
delete all of them, or none of them (and let the orphan handling code
do all the work).
