Mark Goddard 0fc104eeea Invalidate provider tree when compute node disappears ... There is a race condition in nova-compute with the ironic virt driver as nodes get rebalanced. It can lead to compute nodes being removed in the DB and not repopulated. Ultimately this prevents these nodes from being scheduled to. The issue being addressed here is that if a compute node is deleted by a host which thinks it is an orphan, then the resource provider for that node might also be deleted. The compute host that owns the node might not recreate the resource provider if it exists in the provider tree cache. This change fixes the issue by clearing resource providers from the provider tree cache for which a compute node entry does not exist. Then, when the available resource for the node is updated, the resource providers are not found in the cache and get recreated in placement.
