Forward request information to Acceptor#accept (to get the client ip)

[whyoleg]

Hi, thanks for report! This is something what could be provided (rsocket-java has access to SocketAddress from connection for example). But this way it will not work for rsocket-kotlin as I don't want to introduce some kind of multiplatform address functionality in rsocket-kotlin.
But, I've done some experiments on how it could be done in rsocket-kotlin. Just to give more info: we need to keep in mind, that soon we will have support for Resume, in which case we need to have not a single context value per acceptor, but it should be something like StateFlow<Context>. As you said, if server is behind load balancer, in this case after resume we could have even different server, or f.e. we need to somehow ensure, that we point to the same server to make resume work.
Also I want to keep in mind, that some time in the future we will have client LoadBalance API in rsocket-kotlin (as there is such in rsocket-java) and we need to support different transports (tcp/ws/quic) in single LoadBalancer instance while having different contexts per transport.

I will keep in touch here about progress and this most likely will be done in next release with new transport API implementation. No release date yet, because of lack of resources...
