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.

User for Backup Provider

Description

This role sets up a dedicated backup user (backup) for performing secure backup operations. It creates the user, configures a restricted SSH environment with a custom authorized_keys template and an SSH wrapper script, and grants necessary sudo rights for executing rsync. This configuration helps ensure controlled and secure access specifically for backup processes.

Overview

The role is a critical component in a secure backup scheme. By isolating backup operations to a dedicated user, it minimizes the risk of unauthorized actions. The role configures the SSH environment so that only specific, allowed commands can be executed, and it sets up passwordless sudo rights for rsync, ensuring smooth and secure backup operations.

Purpose

The purpose of this role is to enhance the security of your backup system by providing a dedicated user with strict command restrictions. This controlled environment limits the potential damage from a compromised backup account while still allowing efficient backup operations.

Features

User Creation: Creates a dedicated backup user with a home directory.
SSH Environment Setup: Establishes a secure .ssh directory and deploys a restricted authorized_keys file via a Jinja2 template.
SSH Wrapper Script: Implements a custom SSH wrapper that logs and filters incoming SSH commands, enforcing security policies.
Sudo Configuration: Grants passwordless sudo rights for rsync, enabling secure and automated backup transfers.
Integration: Supports seamless integration with your backup infrastructure by limiting the backup user's permissions to only the required commands.
