Create plugin/pkg/transport that holds the transport related functions.
This needed to be a new pkg to prevent cyclic import errors.
This cleans up a bunch of duplicated code in core/dnsserver that also
tried to parse a transport (now all done in transport.Parse).

* plugin/forward: add HealthChecker interface
Make the HealthChecker interface and morph the current DNS health
checker into that interface.
Remove all whole bunch of method on Forward that didn't make sense.
This is done in preparation of adding a DoH client to forward - which
requires a completely different healthcheck implementation (and more,
but lets start here)

With this change the original truncated message returned by requested
server is returned to the client, instead of returning an empty dummy
message with only the truncation bit set.
