the ocata nova.conf template lists pci_passthrough_whitelist in a wrong topic

[Gábor Mészáros]

according to https://docs.openstack.org/ocata/config-reference/compute/config-options.html#id41

the `pci-passthrough-whitelist` should be defined under the [pci] topic, instead of the [DEFAULT], and as `passthrough_whitelist`

[Chris MacNaughton (chris.macnaughton)]

Fortunately, things in [DEFAULT] are implicitly available under every other key that doesn't override it, so:

[DEFAULT]
thing = 1

[other]
thing2=2

would make the keys available like:

{
  DEFAULT: {
    thing: 1
  },
  other: {
    thing: 1,
    thing2: 2
  }
}
