kube-capacity ignores some repeated filter arguments

[frankjkelly]

I am trying to AND conditions but I noticed that when I provide two --node-labels arguments it only pays attention to the last ne

$ kube-capacity --node-labels karpenter.sh/nodepool=karpenter-pulsar-node-karpenter-node --sort cpu.util  | wc -l
      31
$ kube-capacity --node-labels beta.kubernetes.io/instance-type=c6a.8xlarge --util --sort cpu.util  | wc -l
      49
$ kube-capacity --node-labels karpenter.sh/nodepool=karpenter-pulsar-node-karpenter-node --node-labels beta.kubernetes.io/instance-type=c6a.8xlarge --util --sort cpu.util  | wc -l
      49
$ kube-capacity --node-labels beta.kubernetes.io/instance-type=c6a.8xlarge --util --node-labels karpenter.sh/nodepool=karpenter-pulsar-node-karpenter-node --sort cpu.util  | wc -l
      31

Probably the documentation should be adjusted to clarify or perhaps the command line should reject it or warn?
