[Outlook integration] part 2 : GetMessages (#9612)

### Introducing

- mock files in order to setup unit test on parsing outlook messages
- special spec files for development purposes : dev.spec files. They are

format
- main functionality : getMessages. We use microsoft default client to
do so, using the $batch endpoint to group calls by 20
