Use dnsmasq and configure dns server config for clients

Browse Source 
This will add a DNS config to the client configurations pointing to the
wireguard server. With this configuration, all DNS requests are sent
through the VPN and are no longer answered by the local DNS server.

Each client now has a hostname like <device>-client<id>.
