title: Is there a way to use an http proxy for google-cloud-cpp?
body: <p>I am using <a href="https://github.com/googleapis/google-cloud-cpp" rel="nofollow noreferrer">google-cloud-cpp</a> (C++ API for Google Cloud Platform functions) to create/read/write to buckets. When I am working from within the organization's firewall, I have to use a proxy to be able to connect to google cloud.
  I see that we can configure a proxy using the gcloud command line:
  gcloud config set proxy/type http
  gcloud config set proxy/address x.x.x.x
  gcloud config set proxy/port </p>
  
  <p>Can I do something similar when I use google-cloud-cpp?</p>
