Markus Lehtonen c3da439d21 source/memory: implement FeatureSource 
Separate feature discovery and creation of feature labels.

Generalize the discovery of nvdimm devices so that they can be matched
in custom label rules in a similar fashion as pci and usb devices.
Available attributes for matching nvdimm devices are limited to:

- devtype
- mode

For numa we now detect the number of numa nodes which can be matched
agains in custom label rules.

Labels created by the memory feature source are unchanged. The new
features being detected are available in custom rules only.

Example custom rule:

  - name: "my memory rule"
    labels:
      my-memory-feature: "true"
    matchFeatures:
      - feature: memory.numa
        matchExpressions:
          "node_count": {op: Gt, value: ["3"]}
      - feature: memory.nv
        matchExpressions:
          "devtype" {op: In, value: ["nd_dax"]}

Also, add minimalist unit test.
