Unify RpcStyle message routing

Introduces types that makes it easier to perform Rpc-like interactions with Networking.

• RpcMessage trait marks messages that carry a CorrelationId. A sane default correlation id is provided as RequestId.
• RpcRequest trait defines request messages and their response types.
• RpcRouter<T: RpcRequest> enables sending rpc request and awaiting responses with auto eviction of dropped requests.
• ResponseTracker is a helper that manages tracking tokens for in-flight requests, this can be used in the future to replace large portions of IngressDispatcher.
• Macros to help define RPC messages to reduce code noise in node-protocol
