Elasticsearch module functions should pass hosts and profile to index_exists()

[onlyanegg]

The Elasticsearch index_delete execution module is broken when passing a profile in through the arguments. It fails with Exception: Could not connect to Elasticsearch host/ cluster ['127.0.0.1:9200'], is it unhealthy?.
The index_delete() method calls the index_exists() method without passing hosts and profile causing _get_instance() to fail when attempting to ping the ES node.

Setup

delete__index:
   module.run:
     - name: elasticsearch.index_delete
     - index: index_name
     - profile:
         hosts:
           - 'https://{{ user }}:{{ passwd}}@{{ host }}:9243'
