[Process] Normalize exceptions

Bug fix: no
Feature addition: no
Backwards compatibility break: no
Symfony2 tests pass: yes
License of the code: MIT

There were some exceptions in the Process scope but they were not implemented everywhere in the component.

This PR ensure that all exceptions thrown inside Process implements `Process\Exception\ExceptionInterface`.
