Describe the feature:
Document versioning is not supported when indexing documents through ingester pipelines. One possible use case would be log entries are formatted in JSON where one of it's attributes indicate the document version. Since org.elasticsearch.ingest.PipelineExecutionService uses an IndexRequest, it might be helpful to pair this with a version processor to indicate which field of the data being captured can be used as the document version and which versioning type to use.
