Ingest changesedit

Making JsonProcessor stricter so that it does not silently drop data

The ingest node’s json processor was previously lenient. It would accept invalid JSON data if it started with valid JSON data. Anything after the valid part would be silently discarded. From 8.7 onwards, the default behavior is to reject invalid JSON data with an exception so that data is not silently lost. The old behavior can be reproduced by passing false as the value of the new strict_json_parsing processor parameter. We consider this change to be a bugfix but list it here as a breaking change since it may affect the behavior of applications which were sending invalid JSON data to the json processor.

Ensure your application only sends valid JSON data to the json processor, or modify the json processors in your pipelines to set the strict_json_parsing parameter to false.
