* Add Supervisor connectivity check after DNS restart
When the DNS plug-in got restarted, check Supervisor connectivity
in case the DNS plug-in configuration change influenced Supervisor
connectivity. This is helpful when a DHCP server gets started after
Home Assistant is up. In that case the network provided DNS server
(local DNS server) becomes available after the DNS plug-in restart.
Without this change, the Supervisor connectivity will remain false
until the a Job triggers a connectivity check, for example the
periodic update check (which causes a updater and store reload) by
Core.
* Fix pytest and add coverage for new functionality
* 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
