> We have several different timeouts, but in most cases users just want to set something
that is large enough that they can avoid GC pauses. We should have a single conf "spark.network.timeout"
that is used as the default timeout for all network interactions. This can replace the following
timeouts:
> spark.core.connection.ack.wait.timeout
> spark.akka.timeout  
> spark.storage.blockManagerSlaveTimeoutMs  (undocumented)
> spark.shuffle.io.connectionTimeout (undocumented)
> Of course, for compatibility we should respect the old ones when they are set. This idea
was proposed originally by [~rxin] and I'm paraphrasing his suggestion here.
