Separate feature discovery and creation of feature labels. Generalize
the feature discovery so that network devices can be matched in custom
label rules in a similar fashion as pci and usb devices. Available
attributes for matching are:
- operstate
- speed
- sriov_numvfs
- sriov_totalvfs
Labels created by the network feature source are unchanged. The new
features being detected are available in custom rules only.
Example custom rule:
- name: "my network rule"
labels:
my-network-feature: "true"
matchFeatures:
- feature: network.device
matchExpressions:
"operstate": { op: In, value: ["up"] }
"sriov_numvfs": { op: Gt, value: ["9"] }
Also, add minimalist unit test.
