title: How to create a redis cloud connection url with an auth password
body: <p>I'm switching over from a heroku addon to a direct redis cloud account and am a bit puzzled on how to generate the redis url with the auth info.</p>
  
  <p>The old heroku add-on url was in the format of <code>redis://rediscloud:mypassword@redis...</code></p>
  
  <p>However in the dashboard and documentation I don't see any mention of a username to go along with the password.  Do I still set <code>rediscloud</code> as the username in my new account and connection string.  Does it even matter what I set as the username there?</p>
