Kevin Veen-Birkenbach 5e550ce3a3 sys-ctl-rpr-docker-soft: switch to STRICT label mode and adapt tests

- script.py now resolves docker-compose project and working_dir strictly from container labels
- removed container-name fallback logic
- adjusted sys-ctl-hlth-docker-container to include sys-ctl-rpr-docker-soft
- cleaned up sys-svc-docker dependencies
- updated unit tests to mock docker inspect and os.path.isfile for STRICT mode

Refactor systemctl services and timers

Docker Container Health Check

Description

This role monitors the health status of Docker containers on the system. It detects containers that are either unhealthy or have exited with a non-zero code, and triggers alerts if issues are found.

Overview

The role installs a health check script along with a systemd service and timer to run these checks at scheduled intervals.
If unhealthy or failed containers are detected, the configured failure notifier (via sys-ctl-alm-compose) is triggered.

Purpose

The primary purpose of this role is to ensure that Docker-based services remain operational. By automatically monitoring container health, it enables administrators to react quickly to failures, reducing downtime and preventing unnoticed service degradation.

Features

Automated Health Checks: Detects containers in unhealthy state or exited with non-zero exit codes.
Systemd Integration: Installs a one-shot service and timer to run health checks on a schedule.
Alerting Support: Works with the sys-ctl-alm-compose role for failure notifications.
Configurable Script Location: Controlled via the PATH_ADMINISTRATOR_SCRIPTS variable.
