Adding Loki and Promtail

Followed this guide from Techno Tim. Non-tracked changes include:

1. docker plugin install grafana/loki-docker-driver:latest --alias loki --grant-all-permissions to install the Loki docker plugin.
2. Edit /etc/docker/daemon.json to add the following block:

{
    "live-restore": true
    "log-driver": "loki",
    "log-opts": {
        "loki-url": "http://localhost:3100/loki/api/v1/push",
        "loki-batch-size": "400"
    }
}

3. Refer to the documentation for [restarting the docker daemon](/docs/Restart the Docker Daemon.md)
