Description

Spark sets up actors for akka with a set of variables which are defined in the AkkaUtils.scala class.

A snippet:

 98       |akka.loggers = [""akka.event.slf4j.Slf4jLogger""]
 99       |akka.stdout-loglevel = "ERROR"
100       |akka.jvm-exit-on-fatal-error = off
101       |akka.remote.require-cookie = "$requireCookie"
102       |akka.remote.secure-cookie = "$secureCookie"

We should allow users to pass in custom settings, for example, so that arbitrary akka modifications can be used at runtime for security, performance, logging, and so on.
