[Feature Request]: Disable keep-alive feature for containers, when not in maintenance mode

[systemofapwne]

Description / Beschreibung

When ioBroker crashes, the container keeps running. This is a side effect of maintenance mode, as one can see on this line. If the container keeps running, even though ioBroker crashed, the docker daemon will not automatically restart the container (if configured so). One should therefore either make sure, that ioBroker automatically restarts, when it crashes or make the container stop running in that case.

---

Backgroud: I have two ioBroker instances, my main instance running on my server (incl. redis for states and objects) and a satellite. When the satellite loses connection (restart of main server or loss of network), it times out and ioBroker simply stops running and leaves behind an "empty container".

Image version

v8.1.0
