Stefan Agner 953f7d01d7 Improve DNS plug-in restart (#5999) ...

* Improve DNS plug-in restart

Instead of simply go by PrimaryConnectioon change, use the DnsManager
Configuration property. This property is ultimately used to write the
DNS plug-in configuration, so it is really the relevant information
we pass on to the plug-in.

* Check for changes and restart DNS plugin

* Check for changes in plug-in DNS

Cache last local (NetworkManager) provided DNS servers. Check against
this DNS server list when deciding when to restart the DNS plug-in.

* Check connectivity unthrottled in certain situations

* Fix pytest

* Fix pytest

* Improve test coverage for DNS plugins restart functionality

* Apply suggestions from code review
