Don't set TC when on TCP

Don't set the TC bit when a query enters via TCP, also set the
bufsize to max for TCP. This will help in later patches when we
really check for the client's bufsize and don't use 512 for TCP
queries.
Clarify commandline args and json
Use one client for forwarding dns requests

Don't re-create a dns.Client each time we forward a request, have
a global UDP and TCP client ready.

Also enable single inflight for outstanding queries.
Use singleinflight for etcd queries too

This limits the amount of outstanding queries for the same key
to etcd.
Put singleinflght impl. in its own file

Return NODATA when failing to complete CNAME

Add Rcode testing to the testsuite and test for this. But biggest change
is that NODATA responses are returned when failing to resolve a CNAME.
Because we do have an answer, just not the correct type.
If not records are found return NXDOMAIN

And if the CNAME can't be completed throw something in the
log as this may aid in debugging.
