This will enable code reuse across sources while preventing
packages which are not under 'source' to import it.
subsequent commits will introduce the 'custom' source which
will use the logic.
SR-IOV is a PCI attribute and also non-NIC PCI devices can have it. Therefore,
it is useful to label all PCI devices with that capability.
After this commit the following labels for Intel NICs are overlapping:
feature.node.kubernetes.io/pci-0200_8086.sriov.capable=true
feature.node.kubernetes.io/network-sriov.capable=true

Add new config option for specifying the device label, i.e. the
<device-label> part in
node.alpha.kubernetes-incubator.io/nfd-pci-<device label>.present
The option is a list of field names:
"class" PCI device class
"vendor" Vendor ID
"device" Device ID
"subsystem_vendor" Subsystem vendor ID
"subsystem_device" Subsystem device ID
E.g. the following command line flag can be used to use all of the
above:
--options='{"sources": {"pci": {"deviceLabelFields": ["class", "vendor", "device", "subsystem_vendor", "subsystem_device"] } } }'
User can now configure the list of device classes to detect, either via
a configuration file or by using the --options command line flag.
An example of a command line flag to detect all network controllers and
("main class 0x02) and VGA display controllers ("main" class 0x03 and
subclass 0x00) would be:
--options='{"sources": {"pci": {"deviceClassWhitelist": ["02", "0300"] } } }'
This feature source detects the presence of PCI devices. At the moment,
it only advertises GPUs and accelerator cards, i.e. device classes 0x03,
0x0b40 and 0x12.
The label format is:
node.alpha.kubernetes-incubator.io/nfd-pci-<device label>.present
where <device label> is composed of raw PCI IDs:
<class id>_<vendor id>
