hardware: Disallow writing out-of-range values into sensor-value leaf
One of our boxes started reporting nonsense value of one of the sensors.
This value is way beyond range for sensor-value and it led to crashes
because libyang refused to write such value into the sensor-value leaf
and throwed with LY_EVALID.
Let's hotfix that for now to set value as {over,under}flowed and
sensor's oper-status to nonoperational.
However, the problem of setting the correct value is more complicated
because the valid range for the int32 value in YANG is one thing but the
descriptions gives even more constraints depending on sensor-value-type.

Together with sysrepo, this software provides "general system management" of embedded devices. The target platform is anything that runs Linux with systemd. This runs in production on CzechLight SDN DWDM devices.
This component tracks the overal health state of the system, including various sensors, or the state of systemd units. As an operator-friendly LED at the front panel of the appliance shows the aggregated health state.
Firmware can be updated via RAUC, and various aspects of the system's configuration can be adjusted. This includes a firewall, basic network settings, and authentication management.
For a full list, consult the yang/ directory in this repository.
