Custom environment variables
Following up on @tingletech's MR (https://gitlab.coko.foundation/editoria/editoria/merge_requests/72).
A first draft of variables that comes to mind is the following:
- NODE_ENV
- PORT
- INK_ENDPOINT
- INK_PASSWORD
- INK_USERNAME
- DB_NAME
- DB_USER
- DB_PASSWORD
- DB_HOST
- DB_PORT
Probably also something for our mailer config?
