[graphiql] trace extension data viewer

👋 Just asking a quick question on if this is something that we would want to support in graphiql

In apollo playground there was a trace viewer panel. Is this something that we would be okay supported in the official package?

For more details on the trace extension data you can find that here https://github.com/apollographql/apollo-tracing#example

A ticket in graphql-playground existed for this https://github.com/graphql/graphql-playground/issues/241 and the implementation of that was added https://github.com/graphql/graphql-playground/commit/0e2f56d10167b5ac7188c68f993caee617a8dbbe.
