Dockerfile / Production setup configs
* [ ] Create `Dockerfile` / `docker-compose.yml` to quickly start up development environment with `monerod` and `monero-wallet-rpc` running on testnet.
  This should somehow always be on `master` somehow, so there will need to be a way to download the latest successful build from https://build.getmonero.org/
* [ ] Derived from the above (or the other way round), a setup to run a permanent testnet node. Startup scripts for `monerod` and `monero-wallet-rpc` and cronjob for downloading and running latest build.
* [ ] Suggestions for a production setup, possibly different security levels:
  * [ ] Fool!
  * [ ] Default
  * [ ] Paranoid
