Elastic sync does not work when one monstache is configured with multiple elastic urls and first elastic node is down

[sameerkattel]

when I have a monstache running with config

elasticsearch-urls = ["http://p-mn-ms5:9200","http://s-mn-ms5:9200","http://a-mn-ms5:9200"]

Sync does not work when "http://p-mn-ms5:9200" is down
