control/controlclient: use dnscache.Resolver for Noise client

Browse Source 
This passes the *dnscache.Resolver down from the Direct client into the
Noise client and from there into the controlhttp client. This retains
the Resolver so that it can share state across calls instead of creating
a new resolver.
