This release fixes a regression from v0.31.3 which used the peer's `SocketAddr` to add the peer to
the address book. This swallowed the peer's self-reported port which is important in case of reconnect.
It brings back `NetAddress()` to `NodeInfo` and uses it instead of `SocketAddr` for adding peers.
Additionally, it improves response time on the `/validators` or `/status` RPC endpoints.
As a side-effect it makes these RPC endpoint more difficult to DoS and fixes a performance degradation in `ExecCommitBlock`.
