Feature Proposal: Allow custom registry to get the actual address for registering

[felix021]

Currently custom registry (specified by server.WithRegistry(r)) always get the listen address, even if a registry.Info with Addr set is specified by server.WithRegistryInfo.

But there are cases that the listen address is not accessible from the client. For example, the client might need to use the public IP addresss, which is usually different with the listen address.

registry-etcd solved this with the workaround of manually specifying the public address when initializing the registry, which does not applicable to other registries (for now).

In this proposal, we suggest adding another option to the registry.Info instructing Kitex server to pass the real address to custom registries, which solves this issue for all existing implementations like registry-nacos.

If you are interested in implementing this feature, please kindly prepare a detailed tech plan and reply with your lark id for us.
