Refactor restconf-server SSE support
ServerSseHandler cannot hope to correctly implement SSE transition
because it depends on protocol being used:
- for HTTP/1.1 it needs to integrade with Channel pipeline and disable
normal HTTP requests
- for HTTP/2 it needs to track the streamId on which request was made,
so that RST_STREAM frames correctly terminate the event stream
