PSR-2 compliance

[moufmouf]

The generated DAOs and Beans are not fully PSR-2 compliant.

We should:

• generate DAOs and beans that are PSR-2 compliant
• change unit tests to add PHP-CS-Fixer testing to ensure the DAOs and Beans are PSR-2 compliant

Note: by default, PHP-CS-Fixer ensures PSR-2 + an additional set of rules. We are only aiming for strict PSR-2 compliance (no additional rules)
