If the user did not specify a dns server, set a fallback. Since we
already have multiple servers available on an anycast address, this

A warning is still displayed to remind the user to conscientiously
choose a server and not rely on defaults.

configuregateway and it's gateway.d files represent a specific
functionality that other packages depend on. Thus, it is put into
a package of its own so dependencies can be expressed more properly.

and rename the script to configure-layer3 and the folders to layer3.d.
