Investigate using ansible playbook to deploy and update appstore

Currently, we have to manually log in to appstore instances and run updates by hand. This is fragile and unsafe. What happens if we make a mistake? Will we lose all our users' data?

To solve this:

• Let's develop a strategy that uses ansible to deploy resources.
• Let's also figure out how we can re-deploy an App Store onto a new EC2 but use the existing database and S3 bucket or a copy of same.
