use trust-dns for all DNS queries

Browse source 
Previously we were only using trust-dns for resolving SRV records in
server discovery, and then for resolving the hostname from the SRV
record target if one exists. With the previous behavior, admins need to
ensure that both their system resolver and trust-dns are working
correctly in order for outgoing traffic to work reliably. This can be
confusing to debug, because it's not obvious to the admin if or when
each resolver are being used. Now, everything goes through trust-dns and
outgoing federation DNS should fail/succeed more predictably.

I also expect some performance improvement from having an in-process DNS
cache, but haven't taken measurements yet.

record targets in server discovery.
