* Add server instance to the context in ServerTLS and ServerHTTPS
The problem with the current code is that there's no way to get the server instance inside a plugin.
Because of that "metrics" plugin sets empty "server" label for requests served over TLS or HTTPS.
* use s.Server instead of s
* Added server to the context of grpc requests
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).

* global: move to context
Move from golang.org/x/net/context to std lib's context.
Change done with:
for i in $(grep -l '/context' **/*.go); do sed -e 's|golang.org/x/net/context|context|' -i $i; echo $i; done
for i in **/*.go; do goimports -w $i; done
* drop from dns.pb.go as well
