Fix DigitalOcean cloud-init compatibility and deprecation warnings (#14801)

* Fix DigitalOcean cloud-init compatibility issue causing SSH timeout on port 4160

This commit addresses the issue described in GitHub issue #14800 where DigitalOcean
deployments fail during the "Wait until SSH becomes ready..." step due to cloud-init
not processing the write_files directive correctly.

## Problem
- DigitalOcean's cloud-init shows "Unhandled non-multipart (text/x-not-multipart) userdata" warning
- write_files module gets skipped, leaving SSH on default port 22 instead of port 4160
- Algo deployment times out when trying to connect to port 4160

## Solution
Added proactive detection and remediation to the DigitalOcean role:
1. Check if SSH is listening on the expected port (4160) after droplet creation
2. If not, automatically apply the SSH configuration manually via SSH on port 22
3. Verify SSH is now listening on the correct port before proceeding

## Changes
- Added SSH port check with 30-second timeout
- Added fallback remediation block that:
  - Connects via SSH on port 22 to apply Algo's SSH configuration
  - Backs up the original sshd_config
  - Applies the correct SSH settings (port 4160, security hardening)
  - Restarts the SSH service
  - Verifies the fix worked

This ensures DigitalOcean deployments succeed even when cloud-init fails to process
the user_data correctly, maintaining backward compatibility and reliability.

* Implement cleaner fix for DigitalOcean cloud-init encoding issue

This replaces the previous workaround with two targeted fixes that address
the root cause of the "Unhandled non-multipart (text/x-not-multipart) userdata"
issue that prevents write_files from being processed.

## Root Cause
Cloud-init receives user_data as binary/bytes instead of UTF-8 string,
causing it to fail parsing and skip the write_files directive that
configures SSH on port 4160.

## Cleaner Solutions Implemented

### Fix 1: String Encoding (user_data | string)
- Added explicit string conversion to user_data template lookup
- Ensures DigitalOcean API receives proper UTF-8 string, not bytes
- Minimal change with maximum compatibility

### Fix 2: Use runcmd Instead of write_files
- Replaced write_files approach with runcmd shell commands
- Bypasses the cloud-init parsing issue entirely
- More reliable as it executes direct shell commands
- Includes automatic SSH config backup for safety

## Changes Made
- `roles/cloud-digitalocean/tasks/main.yml`: Added | string filter to user_data
- `files/cloud-init/base.yml`: Replaced write_files with runcmd approach
- Removed complex SSH detection/remediation workaround (no longer needed)

## Benefits
-  Fixes root cause instead of working around symptoms
-  Much simpler and more maintainable code
-  Backward compatible - no API changes required
-  Handles both potential failure modes (encoding + parsing)
-  All tests pass, linters clean

This should resolve DigitalOcean SSH timeout issues while being much
cleaner than the previous workaround approach.

* Fix cloud-init header format for DigitalOcean compatibility

The space in '# cloud-config' (introduced in PR #14775) breaks cloud-init
YAML parsing on DigitalOcean, causing SSH configuration to be skipped.

Cloud-init documentation requires '#cloud-config' without a space.

Fixes #14800

* Revert to write_files approach for SSH configuration

Using write_files is more maintainable and Ansible-native than runcmd.
The root cause was the cloud-config header format, not write_files itself.

* Fix Ansible deprecation and variable warnings

- Replace deprecated network filters with ansible.utils equivalents:
  - ipaddr → ansible.utils.ipaddr
  - ipmath → ansible.utils.ipmath
  - ipv4 → ansible.utils.ipv4
  - ipv6 → ansible.utils.ipv6
  - next_nth_usable → ansible.utils.next_nth_usable

- Fix reserved variable name: no_log → algo_no_log

- Fix SSH user groups warning by explicitly specifying groups parameter

Addresses deprecation warnings that would become errors after 2024-01-01.
All linter checks pass with only cosmetic warnings remaining.

* Add comprehensive protection for cloud-config header format

- Add inline documentation explaining critical #cloud-config format requirement
- Exclude files/cloud-init/ from yamllint and ansible-lint to prevent automatic 'fixes'
- Create detailed README.md documenting the issue and protection measures
- Reference GitHub issue #14800 for future maintainers

This prevents regression of the critical cloud-init header format that
causes deployment failures when changed from '#cloud-config' to '# cloud-config'.

* Add test for cloud-init header format to prevent regression

This test ensures the cloud-init header remains exactly ''#cloud-config''
without a space. The regression in PR #14775 that added a space broke
DigitalOcean deployments by causing cloud-init YAML parsing to fail,
resulting in SSH timeouts on port 4160.

* Refactor SSH config template and fix MOTD task permissions

- Use dedicated sshd_config template instead of inline content
- Add explicit become: true to MOTD task to fix permissions warning

* Fix no_log variable references after renaming to algo_no_log

Update all remaining references from old 'no_log' variable to 'algo_no_log'
in WireGuard, SSH tunneling, and StrongSwan roles. This fixes deployment
failures caused by undefined variable references.

* fix: Correct YAML indentation in cloud-init template for DigitalOcean

The indent filter was not indenting the first line of the sshd_config content,
causing invalid YAML structure that cloud-init couldn't parse. This resulted
in SSH timeouts during deployment as the port was never changed from 22 to 4160.

- Add first=True parameter to indent filter to ensure all lines are indented
- Remove extra indentation in base template to prevent double-indentation
- Add comprehensive test suite to validate template rendering and prevent regressions

Fixes deployment failures where cloud-init would show:
"Invalid format at line X: expected <block end>, but found '<scalar>'"

# Cloud-Init Files - Critical Format Requirements
## ⚠️ CRITICAL WARNING ⚠️
The files in this directory have **STRICT FORMAT REQUIREMENTS** that must not be changed by linters or automated formatting tools.
## Cloud-Config Header Format
The first line of `base.yml` **MUST** be exactly:
```
#cloud-config
```
### ❌ DO NOT CHANGE TO:
- `# cloud-config` (space after #) - **BREAKS CLOUD-INIT PARSING**
- Add YAML document start `---` - **NOT ALLOWED IN CLOUD-INIT**
### Why This Matters
Cloud-init's YAML parser expects the exact string `#cloud-config` as the first line. Any deviation causes:
1. **Complete parsing failure** - All directives are skipped
2. **SSH configuration not applied** - Servers remain on port 22 instead of 4160
3. **Deployment timeouts** - Ansible cannot connect to configure the VPN
4. **DigitalOcean specific impact** - Other providers may be more tolerant
## Historical Context
- **Working**: All versions before PR #14775 (August 2025)
- **Broken**: PR #14775 "Apply ansible-lint improvements" added space by mistake
- **Fixed**: PR #14801 restored correct format + added protections
See GitHub issue #14800 for full technical details.
## Linter Configuration
These files are **excluded** from:
- `yamllint` (`.yamllint` config)
- `ansible-lint` (`.ansible-lint` config)
This prevents automated tools from "fixing" the format and breaking deployments.
## Template Variables
The cloud-init files use Jinja2 templating:
- `{{ ssh_port }}` - Configured SSH port (typically 4160)
- `{{ lookup('file', '{{ SSH_keys.public }}') }}` - SSH public key
## Editing Guidelines
1. **Never** run automated formatters on these files
2. **Test immediately** after any changes with real deployments
3. **Check yamllint warnings** are expected (missing space in comment, missing ---)
4. **Verify first line** remains exactly `#cloud-config`
