Update Jetty to 9.4

- from 9.0.3.v20130506 to 9.4.52.v20230823
- rearrange and reorganize servlets and handlers
  so that the server provides everything
- remove server session attribute
   - we already handle user sessions separately at the moment
- mark services known to be unused as deprecated
- add plugin controller check
  to skip JettyPluginInterface resource if it is null
