Original GitHub issue: https://github.com/netbirdio/netbird/issues/620

Originally assigned to: @mlsmaycon on GitHub.

Describe the problem
A nameserver configuration that points to a peer or an address behind a routing peer may cause connectivity issues and unwanted behavior.

We should be able to check if the DNS settings depend on a peer connection and only apply it once the connection is live again.

To Reproduce
Steps to reproduce the behavior:

Create a nameserver configuration that points to a peer (peer-a)
Ensure that it is resolving all connections
Share that connection with your peers via distribution groups
Disconnect the peer-a

Expected behavior
DNS resolution should never fail. In the event we should rollback the DNS resolver and wait for peer connection to be established

Additional context
We might need to extend the status recorder system or the dns server
