🤔 What's the problem you're trying to solve?

When setting up mock servers running in separate go-routines, it would be useful when the context passed to the scenario Before hooks would be cancellable and be cancelled at the end of the scenario.

✨ What's your proposed solution?

Wrap the scenario context with context.WithCancel() before Before hooks are run and call the cancel() after last After() hook is being called.

⛏ Have you considered any alternatives or workarounds?

currently I achieve this with:

func InitializeScenario(ctx *godog.ScenarioContext) {
	var cancel context.CancelFunc

	ctx.Before(func(ctx context.Context, sc *godog.Scenario) (context.Context, error) {
		ctx, cancel = context.WithCancel(ctx)
		return ctx, nil

	})

	ctx.After(func(ctx context.Context, sc *godog.Scenario, err error) (context.Context, error) {
		cancel()
		return ctx, nil
	})

}

it's not very elegant and gets repeated every time I use godog

📚 Any additional context?

My expectation was that this happens automatically, but only after trawling through the source code and running a couple of experiments it turned out it is not the case.
