Can't add more than one cookie with the same name

Issue

• We have two cookies with the same name, but different paths. One of the headers is being ignored. According to https://javaee.github.io/javaee-spec/javadocs/javax/servlet/http/Cookie.html it should be possible to have multiple cookies with the same name but different paths

  javax.servlet.http.Cookie c = new javax.servlet.http.Cookie("test", "test");
    c.setPath("/test");

    javax.servlet.http.Cookie cc = new javax.servlet.http.Cookie("test", "test");
    cc.setPath("/test2");

    response.addCookie(c);
    response.addCookie(cc);

• Where cookies have the the same name, and path, but different domains, they are ignored. Per https://tools.ietf.org/html/rfc6265#section-5.3 it shouldn't

        Cookie cookie1 = new Cookie("cookie1", "value1");
        cookie1.setDomain("*.cookie1.com");

        Cookie cookie1_1 = new Cookie("cookie1", "value1_1");
        cookie1_1.setDomain("*.cookie1_1.com");

        Cookie cookie2 = new Cookie("cookie2", "value2");
        cookie2.setDomain("*.cook2.com");

        resp.addCookie(cookie1);
        resp.addCookie(cookie1_1);
        resp.addCookie(cookie2);

• We hit the issue UNDERTOW-1489 and JBEAP-16298 and need a fix from Red Hat
