Custom panic handler

When a resolver panics, graphql recovers and puts the error into the generated graphql, which is really nice.

I would like to capture these panics to an external system so that I can identify issues with my code. Is there anyway to provide a function which gets called with the captured panics? If not, do you think it is a common use case and hence worth adding?

Just to be clear I don't think it should change how graphql-go handles the panic, it just allows people to record the panic happened
