DLT-Multinode: Gateway does not recognize reset of passive node

^{Originally posted by **marc-heinlein** October 19, 2023}
**Precondition:**
1. Configure a multinode setup like described [here](https://github.com/COVESA/dlt-daemon/blob/master/doc/dlt_multinode.md)
2. Passive and Gateway node are up and running, Gateway has connected to Passive Node, DLT logs of Passive Node can be received at client connected to GatewayNode

**Action:**
- Reset Gateway Node without proper shutdown (i. e. do not stop dlt-daemon)

**Expected behaviour:**
- Gateway Node recognizes unavailability of Passive node and starts reconnecting

**Observed behavior:**
- Gateway Node does not recognize unavailability of Passive node and no reconnection attempt is started
