Pull request overview
Adds a VM-deployable “observability backend” stack (Docker Compose + configs + bootstrap script) under charts/countly-observability/vm-observability/, intended to run Prometheus/Loki/Tempo/Pyroscope/Grafana behind Caddy with TLS and accept telemetry from external agents.
Changes:
- Added
setup.shto provision a data disk, install Docker, copy uploaded stack files, and start the Compose stack. - Added a Docker Compose definition wiring Caddy, Prometheus, Loki, Tempo, Pyroscope, and Grafana (including Google OAuth via env vars).
- Added service configuration files and Grafana provisioning for datasources/dashboards.
