option to ignore self singed cert on the backend side

[psalty]

This is awesome. Thanks for the code sharing.

it would be nice to have an option to ignore self-signed cert on the backend side.

httpProxy.Transport = &ConnectionErrorHandler{http.DefaultTransport}

to something like

httpProxy.Transport = &ConnectionErrorHandler{&http.Transport{ TLSClientConfig: &tls.Config{InsecureSkipVerify: true}, }}
