Change Actor framework #4
Description
Currently, EAT using Actor(http://docs.paralleluniverse.co/quasar).
But it doesn't provide external communication. So it has limitation to extends.
To have load test, we can run it with multi-JVM.
But. expand to centralized-management(which can command to agents and monitor it) function, Actor model of EAT should have new Actor model(which can communicate with external nodes).
Currently I'm considering it with Akka Actor(http://akka.io).
