Document built-in RDT labels to be deprecated and removed in a future release. The plan is that the default built-in RDT labels would not be created anymore, but the RDT features would still be available for NodeFeatureRules to consume.

The RDT labels are not very useful (they don't e.g indicate if the features are really enabled in kernel or if the resctrlfs is mounted).

@PiotrProkop any thoughts on this?

For now we are consuming RDT labels via our custom worker config, something like this:

   "sources": {
      "custom":[
        {
          "name": "RDTL3CA",
          "labels": {
            "feature.node.kubernetes.io/cpu-rdt.RDTL3CA": "true"
          },
          "matchFeatures": [
           {
             "feature": "cpu.rdt",
             "matchExpressions": {
               "RDTL3CA": {"op": "Exists"}
             }
           }
         ]
        }
      ],

but the plan is to migrate to NodeFeatureRules so it's
/lgtm for me
