In experimental clusters we've observed that a 10 second timeout was insufficient,
despite having a low number of nodes and relatively small workload (16 nodes, <1.5 TB data).
This would cause an entire job to fail at the beginning of the reduce phase.
There is no particular reason for this value to be small as a timeout should only occur
in an exceptional situation.

Also centralized the reading of spark.akka.askTimeout to AkkaUtils (surely this can later
be cleaned up to use Typesafe).

Finally, deleted some lurking implicits. If anyone can think of a reason they should still
be there, please let me know.

[SPARK-959] Explicitly depend on org.eclipse.jetty.orbit jar

Without this, in some cases, Ivy attempts to download the wrong file
and fails, stopping the whole build. See bug for more details.

(This is probably also the beginning of the slow death of our
recently prettified dependencies. Form follow function.)

Note that this may not be the best solution, as I do not understand the root cause of why this only happens for some people. However, it is reported to work.
