GraphQL Tracing

[Sherlouk]

I believe this may live partially here and partially in the dependencies this package relies on but it would be amazing for production use cases if we were able to trace the performance of queries, down to the individual resolvers and such.

Example: https://github.com/apollographql/apollo-tracing

I am not very knowledgeable about the inner working of GraphQL tracing. I will look into it and see what I can do, but it might take a while and I probably need some help.
