[stork-users] dhcp4 service to stork disabled

[Slawek Figiel]

Could you verify the Kea CA can communicate with the DHCPv4 daemon by 
executing this command (you need to press Ctrl+D after calling it) :

```
kea-shell --service dhcp4 status-get
```

If you get the proper status, it means the Kea CA-Kea DHCPv4 connection 
works OK. But if you see the message: "unable to forward command to the 
dhcp4 service: No such file or directory. The server is likely to be 
offline" then the Kea CA or Kea DHCPv4 configuration is incorrect.

No, it isn't. The Kea CA needs to be installed on machine with the Kea 
DHCP daemon and Stork agent.

By default, it is `/etc/kea/kea-dhcp4.conf` but you can customize the 
path by the `-c` flag of Kea DHCP daemon.

No, it isn't. In Kea CA you need provide the socket paths of the 
controlled applications in the "control-sockets" property. See 
https://kea.readthedocs.io/en/latest/arm/agent.html#configuration . In 
Kea DHCPv4 you need to specify "control-socket" property. See: 
https://kea.readthedocs.io/en/latest/arm/dhcp4-srv.html#management-api-for-the-dhcpv4-server 
.
