At the moment Ansible prefers yes/no for module booleans, however booleans in playbooks are still using True/False, rather than yes/no. This changes modifies boolean uses in playbooks (and man pages) to favor yes/no rather than True/False.
This change includes:
- Adaptation of documentation and examples to favor yes/no
- Modification to manpage output to favor yes/no (the docsite output already favors yes/no)
- fixed template (it was the template), adding indentation with Jinja2
- added description of code examples to man-page template (was missing)
- fixed fireball, cron, and debug module examples to confrom
