  * Set ETag HTTP Response Header
  *
  * Set the etag header and stop if the conditional GET request matches.
  * The `value` argument is a unique identifier for the current resource.
  * The `type` argument indicates whether the etag should be used as a strong or
  * weak cache validator.
  *
  * When the current request includes an 'If-None-Match' header with
  * a matching etag, execution is immediately stopped. If the request
  * method is GET or HEAD, a '304 Not Modified' response is sent.
  *
  * @param  string                    $value The etag value
  * @param  string                    $type  The type of etag to create; either "strong" or "weak"
  * @throws \InvalidArgumentException If provided type is invalid
