system: Move lldp-systemd-networkd-sysrepo to velia

We agreed that maintaining standalone lldp-systemd-networkd-sysrepo
project is excessive. For example, many compilation units in the
project are copied from velia. Also, velia manages a lot of
system (and network) related things so why should the access to LLDP
neighbours via sysrepo be a standalone project?

This commit copies lldp-systemd-networkd-sysrepo project into velia.
The source repository commit is
39bd89ff7e57cd7bf4ebfdab5fce41fb4fdedcf0.

Only necessary stuff was changed (some naming and compilation issues).
We *might* be changing this code soon if our patch for LLDP neighbours
extraction in JSON format[1] is merged into systemd.

Of course, this also needs a br2-external update because this commit
effectively deprecates lldp-systemd-networkd-sysrepo project and it
should not be used in br2-external anymore.

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
