Evaluate moving echo specific terraform-django parts out of the /terraform directory

The critical parts are:
task-definitions/app.json.tmpl: "echo.wsgi"
variables.tf: default = "Echo"
variables.tf: default = "echo-rds-snapshot"
app.tf: django_container_port = 8085

Start by reviewing task-definitions/app.json.tmpl, variables.tf, and app.tf to identify which Echo- and Django-specific values are coupled to the /terraform directory. Determine whether those parts should move and document the resulting decision and scope; the issue does not name a test or command to run.
