.SYNOPSIS
  Removes stack data: volumes and orphans, optionally build artifacts.

.DESCRIPTION
  DANGER: this deletes the TimescaleDB data volume (all telemetry data),
  the MQTT log volume, and the Loki volume. Users/groups/sessions stored
  in Postgres are deleted with it.

  -Volumes     remove the named volumes (data loss!)
  -All         additionally remove images and build cache
