  Stacked on/Depends on: #128

  This is a reorganization of [PR-123](#123)

  - I've reorganised the commits
  - I've implemented [Solution 1](#127 (comment)) discussed [here](#127 (comment)). The application can get the configuration from the `config.toml` file or from an env var `TORRUST_TRACKER_CONFIG` with the same content as the `config.toml` file. I think it's the minimum change to deploy the application using docker easily.

  The idea is the same as the solution implemented by @Power2All [here](https://github.com/Power2All/torrust-axum/tree/master/docker). But I'm using only one env var. This way, we do not need to change the code if the configuration changes. On the other hand, we are discussing a new implementation for the [settings](#127), and I did not want to implement things that will need to be changed afterwards. I'm also a fan of small steps :-).

  ## Testing

  I have deployed the application to the Digital Ocean App Platform:

  https://lobster-app-dc6o9.ondigitalocean.app/api/stats?token=MyAccessToken

  with [this PR branch docker image](https://hub.docker.com/layers/josecelano/torrust-tracker/docker-reorganized-pr/images/sha256-d08ccf6183c451910ba3dfb74695108700b1aaa2dd13f85bf6f0bdecc4bf43d9?context=repo).

  If you want to test the feature of getting the configuration from an env var locally (without docker):

  ```s
  TORRUST_TRACKER_CONFIG=`cat config.toml` cargo run
  ```

  With docker, you only need to follow the instructions in the README:

  ## Notes

  Digital Ocean App Platform only allows you to expose one port (0.0.0.0:8080). I've deployed it exposing only the API with this configuration:

  ```toml
  log_level = "info"
  mode = "public"
  db_driver = "Sqlite3"
  db_path = "data.db"
  announce_interval = 120
  min_announce_interval = 120
  max_peer_timeout = 900
  on_reverse_proxy = false
  external_ip = "0.0.0.0"
  tracker_usage_statistics = true
  persistent_torrent_completed_stat = false
  inactive_peer_cleanup_interval = 600
  remove_peerless_torrents = true

  [[udp_trackers]]
  enabled = false
  bind_address = "0.0.0.0:6969"

  [[http_trackers]]
  enabled = false
  bind_address = "0.0.0.0:7070"
  ssl_enabled = false
  ssl_cert_path = ""
  ssl_key_path = ""

  [http_api]
  enabled = true
  bind_address = "0.0.0.0:8080"
  ssl_enabled = false
  ssl_cert_path = ""
  ssl_key_path = ""

  [http_api.access_tokens]
  admin = "MyAccessToken"
  ```

  I suppose you need to create three apps sharing the state with a MySQL service if you want to deploy all the services. You want to do the same if you want to deploy more than one UDP or HTTP tracker.
