Apply ansible-lint improvements (#14775)

* Apply ansible-lint improvements with light touch

- Fix syntax errors in playbooks by properly structuring them
- Fix YAML indentation in cloud-init base.yml
- Update ansible-lint configuration to be stricter but reasonable
- Add requirements.yml for Ansible collections
- Skip role-name rule for now due to many cloud-* roles

* Fix playbook syntax errors - proper task-only structure

- Reverted playbook structure since these files are imported as tasks
- Fixed indentation issues throughout cloud-pre.yml and cloud-post.yml
- Aligned module parameters and when clauses properly
- Removed FQCN for now to keep changes minimal

* Fix final YAML indentation and formatting issues

- Fixed cloud-post.yml indentation (8 spaces to 4)
- Added newline at end of requirements.yml
- All syntax checks now pass
