Review comment:
There is no need to store the intermediary result:
```scala
override def getHealthResponse(): Future[JsObject] = allInvokers.map(_.map {
case (instance, state) => s"invoker${instance.toInt}" ->
state.asString
}.toMap.toJson.asJsObject)
```
Also please refrain from using java style getter names like
`getHealthResponse`. I suggest `LoadBalancer.healthStatus()`.
