Refactored automatic DNS resolver configuration
- Doing a DNS probe to make sure the upstream DNS server is reachable
- Using 8.8.8.8 a the default upstream DNS on all platforms
- DOCKSAL_DNS_UPSTREAM can be used to override the default upstream DNS server
- Automatic DNS resolver can now be disabled via DOCKSAL_NO_DNS_RESOLVER=true
- Set interface metric on Windows. This makes sure our VBox adapters is the first in the list and thus it's DNS server settings will be used by Windows
- Adding configure_resolver "off" mode. This will revert resolver settings when the VM is stopped, killed, removed
- Added a flag to control query logging in docksal-dns
- Updated docs regarding the DNS resolver
