Feature request: Cache Control

[steebchen]

Apollo server provides a @cacheControl directive and a info.cacheControl.setCacheHint method to respectively define and dynamically set caching rules. They can be respected by a CDN (public), a client (private) or both, and it allows fine-grained cache control down to a single field.

While this is probably not a super easy thing to add, I wanted to suggest it in general. It would be very nice for apps with high load (even only on specific paths/fields).

@vektah is it possible to mark this issue as never-stale?

It would be really good if gqlgen handler.GraphQL could look at cacheControl requestContext key and include on header max-age request it values. Something like https://github.com/apollographql/apollo-server/tree/master/packages/apollo-cache-control

Based on that, we could define on our root resolver to include cache control of this query only and obtain frontend caching(nginx) without problem, which always look to header max-age setup.
