Adds Promtail and Loki to the metrics stack, configuring them as a datasource in grafana on deployment
Adds a dashboard to monitor the system (logs for producer and consumer)
Restructures the base directory so deployment manifests are moved into a deployments folder
Adds selective labels to producer, consumer and addon so that their logs are ingested by promtail
