support extensions

[omurphy-repay]

A GraphQL server reponds to: {"query": "query { ping }"} with:

{ "data": { "ping": "pong" },
  "extensions": { "requestId": "488baa5c-be04-49ac-957f-ba739096b229" }
}

When sending the same query request to that server using ZeroQL, the response is:

{
    "query": "query { ping}",
    "data": { "ping": "pong"},
    "errors": null
}

The extensions key is missing from the response, making ZeroQL unsuitable for some integrations.

What graphql server do you use? I have been playing around with HotChocolate and could not figure out how to put some values into the extensions field to test the fix.
