+Return `Receive-Maximum` in `CONNACK` for MQTT v5 clients.
+
+EMQX takes the min value of client's `Receive-Maximum` and server's `max_inflight` config as the max number of inflight (unacknowledged) messages allowed.
+Prior to this fix, the value was not sent back to the client in `CONNACK` message.
