📄 Description

Describe your changes

Because on Android system hard to update DNS settings the system will set our DNS service as permanent DNS server on mobile system.
This PR modify the original logic. Now the DNS service can functional in two different way

the DNS service will start listen when get update from mgm server
the DNS service start listening immediately when it instantiated

In the second case the upstream DNS server will be the DNS servers from the host machine.
The relevant Android code: https://github.com/netbirdio/react-native-app/pull/24

Android

The Android code track the network changes and update the DNS configuration when it has been changed on the host machine. For example when switch from 4G to WIFI.

Test

Because this change refactor the whole logic necessary to test all combination of the supported systems

Mac, Win, Linux, Android
On Linux with WG bind interface and with kernel module support
On Linux with systemd, resolve.conf

Issue ticket number and link

Checklist

Is it a bug fix
Is a typo/documentation fix
Is a feature enhancement
It is a refactor
Created tests that fail without the change (if possible)
Extended the README / documentation, if necessary
