Remove the ability of dns_forward_zones to configure ip listening/allowed ranges

Update documentation to reflect this change.

Change restart behavior to run `systemctl daemon-reload` to adapt to
possible reconfiguration of unit file.

Bug fix in config file - had listen instead of access-control in one
section.
