Kevin Veen-Birkenbach 716ebef33b Refactor task includes and update variable handling for Ansible 2.20 migration

This commit updates multiple roles to ensure compatibility with Ansible 2.20.
Several include paths and task-loading mechanisms required adjustments,
as Ansible 2.20 applies stricter evaluation rules for complex Jinja expressions
and no longer resolves certain relative include paths the way Ansible 2.18 did.

Key changes:
- Replaced legacy once_finalize.yml and once_flag.yml with the new structure
  under tasks/utils/once/finalize.yml and tasks/utils/once/flag.yml.
- Updated all include_tasks statements to use 'path_join' with playbook_dir,
  ensuring deterministic and absolute file resolution across roles.
- Fixed all network helper includes by converting direct relative paths such as
  'roles/docker-compose/tasks/utils/network.yml' to proper Jinja-evaluated paths.
- Normalized MATOMO_* variable names for consistency with the updated variable
  scope behavior in Ansible 2.20.
- Removed deprecated patterns that were implicitly supported in Ansible 2.18
  but break under the more strict variable and path resolution model in 2.20.

These changes are part of the full migration step required to ensure the
infinito-nexus roles remain stable, deterministic, and forward-compatible with
Ansible 2.20.

sshd

Description

This Ansible role configures the OpenSSH daemon (sshd) by deploying a templated sshd_config file. It applies secure, best-practice settings—such as disabling root login, enforcing public-key authentication, and setting appropriate logging levels—to harden remote access and reduce the risk of misconfiguration or lockout.

Overview

Renders sshd_config.j2 into /etc/ssh/sshd_config with customizable options
Sets file ownership (root:root) and permissions (0644)
Automatically reloads and restarts the SSH service via a Systemd handler
Uses a run_once_sys_svc_sshd fact to ensure idempotent execution

Features

Templated Configuration
Delivers a Jinja2-based sshd_config with variables for debug logging and PAM support.
Security Defaults
- Disables password (PasswordAuthentication no) and root login (PermitRootLogin no)
- Enforces public-key authentication (PubkeyAuthentication yes)
- Conditionally sets LogLevel to DEBUG3 when MODE_DEBUG is true
Systemd Integration
Handles daemon reload and service restart seamlessly on configuration changes.
Idempotency
Ensures tasks run only once per play by setting the run_once_sys_svc_sshd fact.
