title: Webpack 5: disableHostCheck
body: <p>im serving webpack bundle for dev with kubernetes and get the following message:</p>
  <pre><code>Invalid Host header
  </code></pre>
  <p>Now i want to disable this with the option disableHostCheck, but it seems in the new version of webpack this option is removed.</p>
  <p>Is there any other possibility?</p>
