Subject: [PATCH] Add state for updating Elasticsearch index templates

To prevent index template from constant or accidential update
add separate salt state to explicit use in order to update.

To use run:
  salt -C 'I@elasticsearch:client' state.sls elasticsearch.client.update_index_templates

+Upgrade operations
+------------------
