With Node Feature Discovery (NFD) opearotr 4.14 the EPC labels have been moved from labels to extended resources of the node. But when we try to configure the extendedResources in NodeFeatureRule resource and apply it, the extendedResources part gets silently remove from the resource.

4.14 

    1.Deploy NFD Operator 4.14
    2.Create NodeFeatureRule resource as described above
    3.Apply the resource
    4.Check the resulting yaml of the resource
    

extendedResources definition is missing 

extendedResources definition gets applied and the labels get created
