Using gock with hystrix

[stlimtat]

Problem:
When I use hystix client, I want an ability to use a framework like https://github.com/h2non/gock to mock traffic for my testing purposes.

gock provides a means of doing roughly

hystrix := NewHystrixClient()
gock.InterceptClient(hystrix)
    gock.New("http://foo.com").
        Get("/bar").
        Reply(http.StatusOK).
        JSON(map[string]string{"foo": "bar"})
