Remove explicit Reactor deps for RSockets

* It looks like we don't need to manage Reactor dependencies in the
RSocket module: the `io.rsocket:rsocket-transport-netty` brings
everything we need, although it doesn't that with its own supported
versions
* Use non-HTTPS url for `example.org` in test config to avoid SSL
handshake
