title: azure media service v3 upload from https url
body: <p>does anyone know how we can upload to azure media service asset from a url without encoding? 
  the video stored on s3 amazon is in mp4 format and I don't need to encode it (it takes time), but I need to upload it to my azure media service and make it public for streaming on client side video players.
  I use asp.net and azure media service sdk.</p>
