* 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
* Fixing panic in case if there's no response
There could be a situation when there's no response after ServeDNS call. With the current implementation, this leads to panic.
* Add comment
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).

* DoH: put in pkg/doh
Factor out the DoH stuff into its own package, add function to request
a DoH response. This can be used by forward (and maybe proxy) to
implement DoH client support.

* Fix max-age in http server
Move the minMsgTTL to dnsutil and rename it MinimalTTL, move some
constants there as well.
Use these new function in server_https to correctly set the max-age
HTTP header.
