How to display default Elasticsearch settings

Display default Elasticsearch settings.

Cluster level

Display cluster settings.

$ curl --silent "http://127.0.0.1:9200/_cluster/settings?pretty=true"
{
  "persistent" : {
    "cluster" : {
      "routing" : {
        "allocation" : {
          "exclude" : {
            "_ip" : "192.168.201.104,192.168.201.105"
          }
        }
      }
    }
  },
  "transient" : { }
}

Display cluster settings including default values.
