Fix NodeFeatureRule templating in cases where multiple matchFeatures
terms are targeting the same feature. Previously, only matched feature
elements from the last matcher terms were used as the input to the
template. However, the input should contain all matched elements from
all matcher terms.
For example, consider the example rule snippet below:
...
labelsTemplate: |
{{ range .pci.device }}vendor.io/pci-device.{{ .class }}-{{ .device }}=exists
{{ end }}
matchFeatures:
- feature: pci.device
matchExpressions:
class: {op: InRegexp, value: ["^03"]}
vendor: {op: In, value: ["1234"]}
- feature: pci.device
matchExpressions:
class: {op: InRegexp, value: ["^12"]}
This rule matches if both a pci device of class 03 from vendor 1234
exists and a pci device of class 12 (from any vendor) exists.
Previously, the template would only generate labels from the devices in
class 12 (as that's the last term). With this patch the template creates
device labels from devices in both classes 03 and 12.
