@Override
    public HttpResponseBuilder headers(Iterable<? extends Entry<? extends CharSequence, String>> headers) {
        return (HttpResponseBuilder) super.headers(headers);
    }
Adds multiple headers to this response. For example:
<pre>{@code
HttpResponse.builder()
            .ok()
            .content("Hello, Armeria")
            .headers(HttpHeaders.of("x-test-header", "foo", "Server", "baz"))
            .build();
}</pre>
