This is a breaking change, since there are some old containers that need
to be removed, and also, if you have a remote monitor instance, you need
to edit the configuration file:

```
-# ------ InfluxDB -----------------------------------------------------
-#INFLUXDB_ADDRESS=http://isard-influxdb:8086
+# ------ Prometheus -----------------------------------------------------
+#PROMETHEUS_ADDRESS=http://isard-prometheus:9090
```

And start the docker-compose as the following in order to remove the
unused containers:

```
docker-compose up -d --remove-orphans
```
