Currently only DHCP, SNMP, Gateways Monitoring, RRD Graphing and Syslog services are restarted on interface changes.

We need to create a generic function that checks all system services: OpenVPN, IPsec, L2TP VPN, PPPoE Server, DNS Resolver, IGMP Proxy, uPnP and Captive Portal, to re-binds them to correct IP address.

We have to create a function `restart_interface_services($interface, $ipproto)` to restart all interface and IPv4/IPv6 related services and also use it to fix #3132

we need to create a separate TODO to check/restart all related services on interface change (+ IPsec, uPnP, Captive Portal etc.)
