Public bug reported:

In ironic scenario, the hypervisor resource usage from nova API is not accurate. When the baremetal node is provisioned successfully，the local_gb，memory_mb， vcpus will be set to zero.
The output of CLI is as follows.

Also `nova hypervisor-stats` will return the inaccurate result. So we should fix the issue.
