This project is inspired by

1) Go's default http package
2) Jitter/Backoff ----> https://aws.amazon.com/blogs/architecture/exponential-backoff-and-jitter/
3) Hashicorp library https://github.com/hashicorp/go-retryablehttp

TODO

1) Test cases for hystrix, basic testing for hystrix client
2) More test cases for http client
3) Add Prometheus metric support on the client

EXAMPLE USAGE

1) HTTP Client
	client := NewHttpClient(10*time.Millisecond, DefaultTransport())
	backoffStratergy := NewExponentialBackoff(2*time.Millisecond, 10*time.Millisecond, 2.0)
	client.SetRetries(3)
	client.SetBackoff(backoffStratergy)


	resp, err := client.Get("/foo/bar")
	if err!=nil{
		resp.Body.Close()
	}

2) Hystrix Client (TODO)
