title: Chrome Extension Config Proxy UserName and Password
body: <p>I am creating a chrome extension for changing proxy settings dynamically. But in "chrome.proxy.settings.set" function its not possible to config userName and password for the proxy. So every time I have to manually enter credentials once settings are changed.</p>
  
  <p>But I found that in <a href="https://chrome.google.com/webstore/detail/proxy-auto-auth/ggmdpepbjljkkkdaklfihhngmmgmpggp" rel="noreferrer">Proxy Auto Auth</a> extension its some how configuring username and password programmatically.  I could not find any documentation on how to do this.</p>
  
  <p>I would be grateful if someone can help on this.</p>
