// Updates a response headers policy. When you update a response headers policy,
// the entire policy is replaced. You cannot update some policy fields independent
// of others. To update a response headers policy configuration:
//   - Use GetResponseHeadersPolicyConfig to get the current policy's
//     configuration.
//   - Modify the fields in the response headers policy configuration that you
//     want to update.
//   - Call UpdateResponseHeadersPolicy , providing the entire response headers
//     policy configuration, including the fields that you modified and those that you
//     didn't.
