title: Removing yaml tags from yaml.dump()
body: <p>Am trying to write a yaml file after reading data from a .cfg file.
  While dumping, the file get dumped with huge metadata that is not desired. When I wasn't using the cfg file, the yaml was not writing any extra tags but after using the configobj module it started dumping extra metadata.</p>
  <p><strong>test.cfg:-</strong></p>
  <pre><code>[okd]
  apiversion = v1
  kind = template
      [[metadata]]
      name = xyz
  </code></pre>
  <p><strong>Python script:-</strong></p>
  <pre><code>from configobj import ConfigObj
  import yaml
  
  config = ConfigObj(&quot;test.cfg&quot;)
  
  with open(&quot;test.yaml&quot;, &quot;w&quot;) as f:
      yaml.dump(config[&quot;okd&quot;], f)
  </code></pre>
  <p><strong>Desired output after dumping:-</strong></p>
  <pre><code>apiversion : v1
  kind : template
  metadata:
      name: xyz
  </code></pre>
  <p><strong>yaml that is getting generated:-</strong></p>
