Set up a team deployment for qa on Dokku

Acceptance Criteria:

• On your team's dokku instance, there is an app
  called team03-qa

  Command:
  
  ```
  dokku apps:create team03-qa
  ```
  
  See: <https://ucsb-cs156.github.io/topics/dokku/>
  

• On your team's dokku instance, you have enabled
  https for team03-qa

  See: <https://ucsb-cs156.github.io/topics/dokku/enabling_https.html>
  

• On your team's dokku instance, you have followed
  the steps to configure your app for postgres

  <https://ucsb-cs156.github.io/topics/dokku/postgres_database.html>
  

• Your team's team03-qa app is configured for
  Google OAuth. This requires creating
  a GOOGLE_CLIENT_ID and GOOGLE_CLIENT_SECRET
  for the app, and the configuring the
  environment variables using dokku config:set ...

  * <https://ucsb-cs156.github.io/topics/oauth/oauth_google_setup.html>
  * <https://ucsb-cs156.github.io/topics/dokku/environment_variables.html>
  

• Your team's team03-qa app is configured with the
  environment variables PRODUCTION=true and
  ADMIN_EMAILS=....

  (Note that we set `PRODUCTION=true` even on the
  qa instance.  This is understandably confusing,
  but if you read the section of the web page linked below about what  `PRODUCTION=true` it should be
  more clear why we do that.)
  
  * <https://ucsb-cs156.github.io/topics/dokku/environment_variables.html>
  

• The main branch is deployed on Dokku at, for example,
  https://team03-prod.dokku-xx-cs.ucsb.edu (substituting your
  own dokku instance number in place of xx)

• A links to your team's qa deployment is added to the top of your team's README.md file, replacing the TODO entry.
