Generate Dockerfile and fly.toml for Fly.io deployment

Generate Dockerfile and fly.toml with fly launch:
fly launch --build-only --no-deploy --name jts

Clean up the Dockerfile and fly.toml:
Comment out the DB stuff in the Dockerfile and change the `CMD` -
this is needed since running as `npm run start` prevents from the node
processes from receiving the `SIGINT` or `SIGTERM` signals, more at:

Leave the app name empty and remove all but region in the fly.toml
