title: Import-values feature in requirements.yaml of Kubernetes-helm is not working
body: <p>I am facing a problem with <a href="https://docs.helm.sh/developing_charts/#importing-child-values-via-requirements-yaml" rel="nofollow noreferrer">helm subcharts</a>, the <code>import-values</code> features in requirements.yaml is not working.</p>
  
  <p><strong>What was done:</strong></p>
  
  <p>created parent chart with following values.yaml</p>
  
  <pre><code># parent's values.yaml file
  myimports:
    myint: 0
    mybool: false
    mystring: "helm rocks!"
  </code></pre>
  
  <p>created subchart1 chart with following values.yaml</p>
  
  <pre><code># subchart1's values.yaml file
  default:
    data:
      myint: 999
      mybool: true
  </code></pre>
  
  <p>created requirements.yaml in parent chart.</p>
  
  <pre><code># parent's requirements.yaml file
  dependencies:
    - name: subchart1
      repository: http://127.0.0.1:8879/charts
      version: 0.1.0
      ...
      import-values:
        - child: default.data
          parent: myimports
  </code></pre>
  
  <p>executed following commands</p>
  
  <pre><code> $ helm package subchart1
   $ helm dependency update parent/
   $ helm dependency build parent/
  </code></pre>
  
  <p><strong>What happens:</strong></p>
  
  <ol>
  <li>both update and build command gets completed successfully.</li>
  <li>subchart1 gets downloaded from local helm server and gets placed in ./parent/charts/ directory</li>
  </ol>
  
  <p><strong>Expected output:</strong></p>
  
  <pre><code># parent's final values
  myimports:
    myint: 999
    mybool: true
    mystring: "helm rocks!"
  </code></pre>
  
  <p><strong>Problem:</strong></p>
  
  <p>The parent chart's values.yaml is not getting updated.</p>
  
  <p>helm version:</p>
