Support for https proxy about kraken

[paulsjohnson91]

Update: most of the query strings are hardcoded to http, when manually updating all of these hardcoded string I got it to work with a https repository but also the http client get function seems to override to http which also had to be updated.

So internally, all urls are hardcoded as http. We use the SendTLS option in package httputil to enable https, which swaps http for https:

// SendTLS sets the transport with TLS config for the HTTP client.
func SendTLS(config *tls.Config) SendOption {
	return func(o *sendOptions) {
		if config == nil {
			return
		}
		o.transport = &http.Transport{TLSClientConfig: config}
		o.url.Scheme = "https"
	}
}

I think as long as you have the correct tls config it should do the right thing. For example, in the example devcluster we pull from dockerhub using https://github.com/uber/kraken/blob/master/examples/devcluster/config/build-index/development.yaml#L8

Yes you're right I was seeing the request in the logs as http because it was falling back to http due to me not adding the correct certificates to the build for my nexus. Thanks for the help

So the problem is solved?
