Enabling tracing wipes extension data, e.g. __queryPlanExperimental

[godspeedelbow]

Spent some time trying to figure out why response.extensions.__queryPlanExperimental was getting removed from the response after it was set.

Basically, when config.tracing is set to true, it includes the TracingExtension which has a format method and which will override whatever was set on response.extensions.

The expected behavior is that extension data does not get wiped. Or if it is the intended behavior, then I think it makes sense if there's an extension hook that gets called with response data, so that an extension can pluck the data it needs, e.g. __queryPlanExperimental and then format that data with the format method.

Can you try again with the latest version of Apollo Server, 2.14.1? The tracing extension was recently ported to the plugin API in Apollo Server 2.14.0 via #3991.

The tracing option and the TracingExtension (which created an old inefficient kind of inline trace) are no longer part of Apollo Server.
