fff-dhcp: add fallback dns server
If the user did not specify a dns server, set a fallback. Since we already have multiple servers available on an anycast address, this address is chosen instead of as specific server. This should avoid the issue that the default server might deprecate suddenly. A warning is still displayed to remind the user to conscientiously choose a server and not rely on defaults.
