[1976] Switch processing to the ClientLists

The authoritative server now uses the ClientLists to provide the correct
data source clients for Query. The previous configuration is now
ignored.

Many tests were disabled. Part of them is because we don't have the
default configuration for built in yet (but it will be simple and solved
in this branch soon, it's just to keep this commit smallish). The more
problematic ones are because our in-memory is not really working well --
we want to use it as a cache and that is missing. Loading the zone files
to in-memory is also missing (ticket #2046).
