Aggregator: add the possibility to not raise an exception invalid rows

[ecourtial]

With the following input sources:

  {
    "id": "1",
    "type": "premium",
    "subscriptionNumber": "p123"
  },
  {
    "id": "2",
    "type": "standard"
  },
  {
    "id": "3",
    "type": "gold",
    "subscriptionNumber": "g234"
  }
]

1;John;Doe;john.doe@acme.com
2;Jane;Does;jane.does@acme.com
3;Bart;Simpson;el-barto@acme.com

I would like extract data into a CSV, with the following columns :

• id
• email
• type
• subscriptionNumber

The result is the following:

1;john.doe@acme.com;premium;p123
3;el-barto@acme.com;gold;g234

The code works as expected, but it throws an exception because there is one invalid row. This is currently the only way to discard invalid rows.

Could we consider to add a flag or something to be able to keep discarding invalid rows but without throwing an exception, because in some use cases, it could be normal to have invalid rows.
