Etcd Cloud Plugin for etcd

The etcd Cloud plugin allow to use etcd for the unicast discovery mechanism.

The purpose of that plugin is to discover the transport adresses of the other Elasticsearch nodes in a cluster with etcd access.

How it works

Let's say you have this configuration stored in etcd :

/services/<<myclustername>>/1/transport: {"host":"127.0.0.1","port":9300} 
/services/<<myclustername>>/2/transport: {"host":"127.0.0.1","port":9301}
/services/<<myclustername>>/3/transport: {"host":"127.0.0.1","port":9302}

With this elasticsearch configuration :

  cloud:
      etcd:
          host: http://localhost:4001
          key: /services/<<myclustername>>
  discovery:
          type: etcd

Then elasticsearch will use unicast discovery and try to connect to the other nodes using the transport addresses set in etcd.
