Add observability stack with Grafana, Prometheus, Loki, and cAdvisor
- Introduced a new Grafana dashboard for monitoring Docker containers using cAdvisor. - Created provisioning files for Grafana dashboards and data sources. - Added Dockerfiles and configuration files for Loki and Prometheus. - Implemented a Docker Compose stack for the observability services. - Configured Traefik as a reverse proxy for the services with appropriate routing. - Added scripts for SSH tunneling to access the telemetry dashboard. - Included secrets management for Grafana admin credentials.
