dont discard logs

## What?

It happens that logs are discarded because the extractor/converter doesn't match. It would be usefull if graylog doesn't discard the logs, instead just skip the extrator thing and add leave the message as is and add an field like 'graylog_note' which can contain the error message (just an example)
> ERROR [CsvConverter] Different number of columns in CSV data (5) and configured field names (6).

with that field you can filter these messages, adjust the extractor and no message will be lost
## Why?

**no** message will be lost, which is very important

## Your Environment

I think it doesn't matter
