Vrmlogger: setting VRM mode to off: send dying wish to VRM

[wiebeytec]

We log the new data attribute vrm (/Settings/Network/VrmPortal) with the VRM mode (off, read-only, full). This way, VRM can see that a device is running in read-only or full mode.

When turning it off, we currently have a bit of a catch-22, because vrmlogger is needed to send the 'off' (0) value. We can make vrmlogger sends this config change on exit, before actually exiting.

If daemon tools sends a proper SIGTERM, we can implement the exit handler as we want, and it should be easy to implement.

vrmlogger is not stopped though, it just no longer logs to the internet, it can still log to sd-cards etc. If I am not mistaken VRM knows if there are no new log records arriving, so I guess it will settle after some time, right?

If a 'no data' alarm trigger is active, it will send out an e-mail after <log interval> + x has expired. This will already happen now when people disable logging to VRM. I just confirmed by disabling logging on a site.

Also, the current communication about 'vrm log mode' is also not perfect. The installation I just tested on already said it was disabled, with a timestamp of '2024-02-27 21:09:19', but it was actually enabled.

In other words, it's already not perfect.
