Actually hold off on merging this -- I found that this patch doesn't
completely solve the problem. The issue I think is that `finishConnect` throws
an IOException [1] if there is a connectTimeout and we don't retry if we hit
any exceptions.
(https://github.com/apache/spark/blob/master/core/src/main/scala/org/apache/spark/network/Connection.scala#L327).
I'll try to test another fix and update this PR.
