[FR] disable tracing by default for introspection queries or graphiql/playground

[frederikhors]

To reproduce:

• git clone https://github.com/frederikhors/iss-async-graphql-error-handling && cd iss-async-graphql-error-handling && cargo run

• Go to http://localhost:8000/graphiql

• Look at the command line: a LOT of lines of tracing!

How to disable those lines? Are them because of GraphiQL or for introspection queries?

Can we disable by default?

I think #841 is for the same, right @nileshmali?

I think 13a66a5 fixes this. I'll try soon.

It's printing only these lines now:

  in async_graphql::graphql::request

So I think it works!

Thanks!
