Brian Clozel 35b0c8b577 Update websocket support for Jetty 9.3+ ...

Due to a few changes in `WebSocketServerFactory` and `Session` API, our
`JettyRequestUpgradeStrategy` and `JettyWebSocketSession` needed to
adapt. As of 9.3.15+ and 9.4.0+, some reflection is required to support
previous versions.

Spring 4.3 websocket officially supports Jetty 9.1 to 9.3.

Issue: SPR-14940
