1.0.0-ALPHA-4 release

1. Switching to Java 11.
2. Performance improvement.
3. Add alpn and sni support for websocks applications.
4. Graalvm support is removed because it does not support java 11.
5. Because we now switches to Java 11, we can provide a smaller runtime.

NOTE: this is still in alpha phase, any configuration or behavior may change without any notification.
