title: 'preview' ingress service configuration
body: <p>I'd like to know how to add annotations on all <code>preview</code> ingress services definition generated for each jx preview to configure it. </p>
  
  <p>I'm having issues with either header forward or header stripping by nginx. The server behind the <code>preview</code> ingress service is not receiving some headers requests.</p>
  
  <p>Thank you for your help!</p>
