Adds a progress indicator for reindex and update_by_query requests that you
can fetch like so:
```

```

```
{
  "nodes" : {
    "r1A2WoRbTwKZ516z6NEs5A" : {
      "name" : "Tyrannus",
      "transport_address" : "127.0.0.1:9300",
      "host" : "127.0.0.1",
      "ip" : "127.0.0.1:9300",
      "attributes" : {
        "testattr" : "test",
        "portsfile" : "true"
      },
      "tasks" : [ {
        "node" : "r1A2WoRbTwKZ516z6NEs5A",
        "id" : 36619,
        "type" : "transport",
        "action" : "indices:data/write/update/byquery",
        "status" : {       <---------------------------- Status is this
          "total" : 6154,
          "updated" : 3500,
          "created" : 0,
          "deleted" : 0,
          "batches" : 36,
          "version_conflicts" : 0,
          "noops" : 0
        },
        "description" : "update-by-query [test][test]"
      } ]
    }
  }
}
```

The progress is just (updated + created + deleted) / total
