title: how to move prometheus adapter to another namespace?
body: <p>For now I have prometheus and prometheus adapter in different namespaces:
  <img src="https://i.stack.imgur.com/9Bm2h.jpg" alt="Text"></p>
  
  <p>I tried to configure adapter YML but I was not successful:
  apiVersion: apps/v1
  kind: Deployment
  metadata:</p>
  
  <pre><code>  annotations:
      deployment.kubernetes.io/revision: "2"
    creationTimestamp: "2020-01-30T08:49:05Z"
    generation: 2
    labels:
      app: prometheus-adapter
      chart: prometheus-adapter-2.0.1
      heritage: Tiller
      release: prometheus-adapter
    name: prometheus-adapter
    namespace: my-custom-namespace
    resourceVersion: "18513075"
    selfLink: /apis/apps/v1/namespaces/my-custom-namespace/deployments/prometheus-adapter
    ...
  </code></pre>
  
  <p>But I see error:</p>
  
  <pre><code>the namespace of the object (my-custom-namespace) does not match the namespace on the request (default)
  </code></pre>
  
  <p>How to fix it ?</p>
