Document sample NETCONF operation
The User's Guide does not have a clear, simple example how to use kea-netconf. We need a simple example that will cover:
- start kea-dhcp4
- load basic config into sysrepo using sysrepocfg
- start kea-netconf and explain what's going on
- change the configuration a bit
- explain how kea-netconf picks up the changes
Also clean up example sysrepo configs (they're in src/bin/netconf/configs, should be moved to doc/examples/netconf).
