[RFE] node affinity range

[halfcrazy]

Is your feature request related to a problem? Please describe.
I have different ranges for different nodes. My workload works in all nodes, I want one config to manage them all.

Describe the solution you'd like

      "ipam": {
        "type": "whereabouts",
        "ipRanges": [{
            "range": "192.168.10.1/24",
            "nodeSelector": {"trie":"t0"}
          }, {
            "range": "176.168.11.1/24",
            "nodeSelector": {"trie":"t1"}
        }]
      }

Describe alternatives you've considered
Multiple network-attach-defs may work. But I want to reuse one config.
