Support Jetty 9.4 and upgrade to 9.4.0.v20161208
Update `JettyEmbeddedServletContainerFactory` to support Jetty 9.4 directly and Jetty 9.3 via reflection. The primary difference between Jetty 9.3 and 9.4 are the session management classes. Websocket suppport has also been updates, but this is handled transparently by the Spring Framework support. Fixes gh-7599
