system: Clear old install message in firmware updates

This patch implements clearing the old install message if new
installation is started. This could be confusing because it is not clear
to which installation the message refers.

Consider the scenario with two consecutive installations via RAUC. The
first installation fails and an error message is set into
/czechlight-system:firmware/installation/message leaf. Then another
installation could be started and while
/czechlight-system:firmware/installation/status correctly contains value
"in-progress", the message leaf still contains the old error message.

YANG System management for embedded devices running Linux

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.

Health tracking

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.

System management

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.

Supported YANG models
