After starting, IoT Manager subscribed to topic "/IoTmanager"
IoT Manager will be receive all messages, published by any devices to this topic.
You can look at IoTmanager4.ino (used ArduinoJson library and more simplest use)
If use "retained" flag for publishing config, we see all devices, include "dead devices", after IoTmanager reconnect.
At now, after HELLO, we receive actual sensor config data only from "live devices" after IoT Manager reconnect.
