As mentioned in [the official blog post](https://webtide.com/conscrypting-native-ssl-for-jetty/), Jetty now supports TLS with Concsrypt, without changing the boot classpath or using a Java agent. The ALPN + HTTP/2 support for that should be shipped with Jetty 9.4.8, so we'll leverage that support for HTTP/2 support in Spring Boot. See eclipse/jetty.project#215
