Please expose WebsocketConnection headers for auditing/security

[bas-velthuizen]

Our application needs to be able to store the client address of a client in a database for any auditable action. When those actions are initiated via an RSocket request, there is no possibility to retrieve the client IP via normal actions.

Of course there are some dirty ways around, like using reflection to expose the connection fields of the RSocket server or the Requester, but this feels like hacking, and reverting the field exposition results in access errors.

(I'm at this moment using the solution in issue #831, which works, but feels hacky)

Can the connection fields or just the headers be exposed in the RSocket and Requester classes instead of keeping them protected?

We're using RSocket 1.1.3 via Spring Boot 3.3.1
