Description

How to reproduce:

1) Configure the interface with Static IPv4
2) Select this interface in the "Network Interfaces" and/or "Outgoing Network Interfaces" list on the Services / DNS Resolver page
3) Disconnect this interface and reboot
3) Check the interface/outgoing-interface entries in /var/unbound/unbound.conf
3) Connect this interface - you'll see the "/rc.linkup: Hotplug event detected for INTERFACE static IP (x.x.x.x)" in logs
4) interface/outgoing-interface entries in /var/unbound/unbound.conf do not have a connected interface IP
5) Same with disconnecting - /var/unbound/unbound.conf still have a disconnected interface IP

Workaround - reboot or restart DNS Resolver

#11547 should be improved
