yang: Introduce ietf-routing module with dependencies

We are also going to implement a model dealing with network routing
tables. Such model (ietf-routing) is published in in RFC 8349 [1].
It needs to be augmented for ipv4/ipv6 routing. All the models are
downloaded from YangModels GitHub repository [2] (commit
8dd16482bb74c6add0b187a0e7755f5549da1ccb).

Also note that ietf-routing (as well as ietf-interfaces) also model
*-state containers which are supposed to be `config false;`. We are
actually using config false too but on the configuration containers.
This is done via augmentation in czechlight-network model.

This, however, led to unpleasant situation where I have not realized
that ietf-routing:routing-state depends on
ietf-interfaces:interface-state and the model could not be installed
into sysrepo (see https://github.com/sysrepo/sysrepo/issues/2384).
The augmentation in czechlight-network model had to be altered as well.

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.
