Fix simulate remove ingest processor throwing illegal_argument_exception

[gaobinlong]

Description

This PR fixes the bug of simulating remove ingest processor always throwing illegal_argument_exception, the bug is caused by the new merged PR which disallowing removing some metadata fields, but when simulating processors, the ingesting document does not have the metadata fields like _version and _version_type, so document.getFieldValue(IngestDocument.Metadata.VERSION_TYPE.getFieldName(), String.class) throws illegal_argument_exception rather than return null value, in order to return null value, use another method instead with setting ignore_missing to true.

Both the unit test code and yml test do not cover this case, I've added some yml tests and unit test code for it.
