dhcpd 4.4 named ddns and additional event triggers

[Rick Dicaire]

Bill, thanks for responding.
I'm looking to update netbox via REST api with dhcp client IPs/hostnames.
I expect to exec a script on each event type that will pass the IP and
hostname data to netbox for updating.
My concern was configuring event actions would stop dhcpd from also
updating named via dhcpd's internal
updating mechanism.
