refactor: Restructure configurable security policy PR

- Move example to examples/20_security_policy/ directory structure
- Rename files to match requested naming convention:
  - configurable_security_policy.py (main example)
  - custom_policy.j2 (example custom policy template)
- Update example code to work with new file structure
- Remove extra files to keep PR focused on essential changes
- Maintain test compatibility with custom_security_policy.j2
