[BUG] Using update, upsert, or delete actions without specifying document_id crashes the pipeline with NPE

[graytaylor0]

Describe the bug
update, upsert, and delete bulk actions in the opensearch sink requires knowing the document_id of the document to update or delete. However, if document_id is not provided in the opensearch sink with one of these actions being used, the following NPE is hit when converting the failed document to a DLQ object

Caused by: java.lang.NullPointerException
	at org.opensearch.dataprepper.plugins.sink.opensearch.dlq.FailedBulkOperationConverter.convertDocumentToGenericMap(FailedBulkOperationConverter.java:64) ~[opensearch-2.6.1.jar:?]
	at org.opensearch.dataprepper.plugins.sink.opensearch.dlq.FailedBulkOperationConverter.convertToDlqObject(FailedBulkOperationConverter.java:38) ~[opensearch-2.6.1.jar:?]
	at java.base/java.util.stream.ReferencePipeline$3$1.accept(ReferencePipeline.java:195) ~[?:?]

Expected behavior
Do not crash the pipeline and send the document to DLQ without any document_id

We should add restrictions to the pipeline configuration to disallow these actions when the customer does not provide a document_id.
