Title: SPARK-2156: Provide more overhead for Akka content in result message.

Previously we only allowed 1 KB of overhead, but in practice it seems like
Akka can insert dozens of KB of overhead. This patch gives more slack,
avoiding the case where we exceed the max frame size and messages
are dropped silently.
