title: Disable Python requests SSL validation for an imported module
body: <p>I'm running a Python script that uses the <code>requests</code> package for making web requests. However, the web requests go through a proxy with a self-signed cert. As such, requests raise the following Exception:</p>
  
  <p><code>requests.exceptions.SSLError: ("bad handshake: Error([('SSL routines', 'SSL3_GET_SERVER_CERTIFICATE', 'certificate verify failed')],)",)</code></p>
  
  <p>I know that SSL validation can be disabled in my own code by passing <code>verify=False</code>, e.g.: <code>requests.get("https://www.google.com", verify=False)</code>. I also know that if I had the certificate bundle, I could set the <code>REQUESTS_CA_BUNDLE</code> or <code>CURL_CA_BUNDLE</code> environment variables to point to those files. However, I do not have the certificate bundle available.</p>
  
  <p>How can I disable SSL validation for external modules without editing their code?</p>
