title: Get current configuration for a running helm release?
body: <p>Let's say that I recently installed or upgraded a helm release, e.g.:</p>
  
  <pre><code>helm upgrade ... config.yaml ...
  </code></pre>
  
  <p>Is there any way for me to retrieve the <code>config.yaml</code> via helm CLI? I need to verify a config value.</p>
