Moved the code for splicing a DHCP range into its dedicated function as this
will later be required again. Having subsequent DHCP exclude addresses
e.g. 192.0.2.70 and 192.0.2.71 did not work as the previous algorithm
created a range whose start address was after the end address.

[wireguard] T1428: correct handling of the fwmark option

Netmasks (both IPv4 and IPv6) that are allowed to use the server. The default
allows access only from RFC 1918 private IP addresses. Due to the aggressive
nature of the internet these days, it is highly recommended to not open up the
recursor for the entire internet. Questions from IP addresses not listed here
are ignored and do not get an answer.
https://docs.powerdns.com/recursor/settings.html#allow-from
Imagine an ISP network with non RFC1918 IP adresses - they can't make
use of PowerDNS recursor.
As of now VyOS hat allow-from set to 0.0.0.0/0 and ::/0 which created an open
resolver. If there is no allow-from statement a config-migrator will add
the appropriate nodes to the configuration, resulting in:
service {
dns {
forwarding {
allow-from 0.0.0.0/0
allow-from ::/0
cache-size 0
ignore-hosts-file
listen-address 192.0.2.1
}
}
}

configuration line
In the past we used the PowerDNS cofniguration option forward-zones and
forward-zones-recurse, but only the latter one sets the recursion bit in
the DNS query.
Thus all recursions have been moved to this config statement.

[pdns-recursor] T1469 - replace forward-zones with forward-zones-recurse
|
|
of CLI mode.
|
|

forward-zones-recurse behaves identically to dnsmasq server option
in legacy vyos 1.1.8, while forward-zones option disallow recursive
name resolving, which leads to dns lookup failure

WPAD url could be configured by CLI but the generated config was not
understood by ISC dhcp - caused by infalid if {} statement resulting in
a missing option wpad-url block.

Add support for relaying a DHCPv6 packet to multiple servers on one upstream
interface.

When generation the configuration for multiple upstream interfaces a whitespace
was missing in the generated configuration:
OPTIONS="-6 -l 2001:db8::ffff%eth1 -u 2001:db8:1:ffff%eth2-u 2001:db8:2:ffff%eth3"
^---
This caused an error when starting up the DHCPv6 relay service
