title: Add servers/platforms from backend in Aegir using drush
body: <p>I'm looking for automating the process of creating new server, installing packages, adding server and platform to Aegir host. I know how to do it with GUI for adding server and platform but not sure to do it from backend(CLI) using drush. Would be great if someone can provide me some reference if they are into this process.</p>
  
  <p>Thanks,
  Swaroop.</p>
