Solution notes
The fix effects new DXP installations only. Existing deployments where the Workflow Metrics indexes have already been created in Elasticsearch have to update the index settings manually.

---

Reproduction Steps:

1. Start up 3 Elasticsearch 6 nodes
   1. Edit
      ES_HOME/config/elasticsearch.yml

      cluster.name: LiferayElasticsearchCluster
      discovery.zen.minimum_master_nodes: 2
      node.max_local_storage_nodes: 3
      

   2. Start the same Elasticsearch from 3 terminals (./bin/elasticsearch): this will create a 3-node cluster using a single installation, suitable for testing
2. Start up DXP 7.2 SP2
3. Go to Control Panel -> Configuration -> System Settings -> Search -> Elasticsearch 6
   1. Specify all the 3 transport addresses: localhost:9300, localhost:9301, localhost:9302
   2. Configure it to be Remote
4. Go to Control Panel -> Configuration -> Search and confirm it is not using Embedded nodes
5. Reindex all Search Indexes
6. Open a terminal and run

   curl -X GET "localhost:9200/_cat/indices/*?v&s=index&pretty"
   

   Expected Result: workflow-metrics indexes have at least 1 replica
   Actual Result: workflow-metrics indexes have no replicas.
