It was used while migration the production server and since this one and
production configs are almost exact copies (just rails_env differs) it's
no longer needed.
And this brings simplicity back to this repo.
The most noticeable change is the removal of `url` from production's
database config as DATABASE_URL got removed in
https://github.com/coopdevs/timeoverflow-provisioning/pull/21 two years
ago and it's true in production:
```
timeoverflow@timeoverflow-production:~$ env | grep DATABASE
DATABASE_NAME=xxx
DATABASE_USER=xxx
DATABASE_PASSWORD=xxx
```
This is the upgraded server we are setting up to host the app. Time to
deploy and start testing! 🎉
The Capistrano environment is tightly coupled with Rails environments so
we need to add a new one called `next`.
