Database anonymization config+command

This is a feature proposal:

- allow user of this bundle to define some configuration that would looks like:

```
ekino_data_protection:
...
data_anonymization:
anonymize:
first_table_name_containing_private_data:
- firstName: 'fakeValue'
- lastName: 'fakeValue'
- email: 'fakeEmail-@fake.com' (pattern to avoid fail with unique primary keys)
second_table_name_containing_private_data:
...
truncate:
- first_table_name_to_truncate (like session or basket tables that has no sense to keep)
```

then with this config we can provide a generic command to anonymize a database

WDYT?
