title: Omit labels from series results PromQL
body: <p>Suppose I write a basic PromQL query like this </p>
  
  <p>Query:
  <code>kube_deployment_spec_replicas{}</code> </p>
  
  <p>Result:
  <code>kube_deployment_spec_replicas{deployment="mydeployment",endpoint="myendpoint",instance="myinstance",job="myjob",namespace="default",pod="mypod",service="myservice"}</code></p>
  
  <p>Is there a clean way to omit <code>instance</code> and <code>pod</code> from the resulted timeseries?</p>
  
  <p>Desired:
  <code>kube_deployment_spec_replicas{deployment="mydeployment",endpoint="myendpoint",job="myjob",namespace="default",service="myservice"}</code></p>
