Agent is deprecated with Akka 2.5, so refactor where it is used

[anilgursel]

With Akka 2.5, Agent is deprecated. Please see http://doc.akka.io/docs/akka/current/scala/project/migration-guide-2.4.x-2.5.x.html#agents.

It is being used in squbs-unicomplex for keeping state. We need to refactor it.

There is no substitute for Agents, right? How are we planning to fix this?

[anilgursel]

Agent usage in Unicomplex is pretty small. We have not spend anytime on how to replace it but multiple design choices can be there. We can try to keep the state in an Actor instead. If you have any suggestions, please share.

If this were to be replaced with an Actor, would one use an Await.result(actor ? get, duration)? What other possibilities would one have?

[akara]

Can you please let us know your use of Agent. Will take a look how this can be fixed. No, you would not want to await either an agent or an Actor.

@akara No use case of mine, I thought I could try to work on this issue if I knew how to replace the Agent. :)
The use case would be in TimeoutPolicy for Metrics, and Unicomplex.
