If you set your version as 5, it was trying to use _status but that wont work. So lets just use _status if we have the version set as one.

Much easier for future support.

Otherwise you get errors such as

curl http://localhost:9200/_status
{"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"No endpoint or operation is available at [_status]"}],"type":"illegal_argument_exception","reason":"No endpoint or operation is available at [_status]"},"status":400}
