[Pull-based Ingestion] disable push-API for indexing in ingestionEngine

[yupeng9]

Description

The indexing API call will fail for ingestion engine. For example

curl -X PUT -H 'Content-Type: application/json' http://localhost:9200/my-index/_doc/1 --data '
{
  "name": "John Doe",
  "age": 24
}
'

returns

{"error":{"root_cause":[{"type":"unsupported_operation_exception","reason":"push-based indexing is not supported in ingestion engine, use streaming source instead"}],"type":"unsupported_operation_exception","reason":"push-based indexing is not supported in ingestion engine, use streaming source instead"},"status":400}%

I think this should be a 4xx error code, not a 500, right?

500

right, ideally it shall be 4xx to indicate client-side error. is it possible to catch the thrown exception and change error code somewhere?
