/**
  * [[com.stratio.crossdata.common.util.akka.keepalive]] object provides the tools to easily implement a dead man switch
  * (https://en.wikipedia.org/wiki/Dead_man%27s_switch) for actors. This dead switch is not dependant on
  * low-level details, neither on the actor reference or address within an ActorSystem, remoting or akka clustering
  * mechanisms.
  *
  * Each monitored actor provides a customized id whereby the [[KeepAliveMaster]] or controller identifies it.
  * Any akka actor can make use of the stackable modificator [[LiveMan]] trait to automatically become
  * a monitored actor.
  *
  * The monitor is itself an actor which notifies heartbeat losses by the means of [[keepalive.KeepAliveMaster.HeartbeatLost]]
  * events.
