Support for response.body.extensions on successful response?

[JustinSomers]

What happened?

We are trying to replicate the behavior of our Apollo Server based subgraphs. We commonly use the response.body.extensions property from apollo server to add additional information such as additional codes that may occur even on a "successful" response.

Currently, I am able to add extensions parameters by using:

graphql.AddError(ctx, &gqlerror.Error{
	Path:    graphql.GetPath(ctx),
	Message: e.Payload.Message,
	Extensions: map[string]interface{}{
		"code":            e.Payload.Code,
		"status":          e.Payload.Status,
		"ErrorCode": e.Payload.ErrorCode,
	},
})

However, it would be valuable to also to add to the extensions object when a success is returned too.

What did you expect?

Something like graphql.AddExtensions(ctx, myCustomExtensionObject) would be helpful.
