Tracking issue for SocketAddr setters

[SimonSapin]

#31083 adds set_ip and set_port methods to SocketAddr, SocketAddrV4, and SocketAddrV6; as well as set_flowinfo and set_scope_id on SocketAddrV6. They are all fairly straightforward and correspond to existing getter methods.

As all new additions, they will be #[unstable] for now.

Seems like 'B-unstable' is the most appropriate label for this issue? There's no RFC, but this is a stability-tracking issue.

[SimonSapin]

Yes. I would have set it, but you need write access to a repository to set labels :)
