This commit adds the name of the current pipeline to ingest metadata.
This pipeline name is accessible under the following key: '_ingest.pipeline'.

Example usage in pipeline:
PUT /_ingest/pipeline/2
{
    "processors": [
        {
            "set": {
                "field": "pipeline_name",
                "value": "{{_ingest.pipeline}}"
            }
        }
    ]
}
