[SPARK-4134] Dynamic allocation: Tone down kill error messages
Right now we get a bunch of scary error messages if the user kills
executors himself (or uses dynamic allocation to do so):
This patch tones down these error messages, since these are really not
errors.
I could not figure out how to remove the `WARN` at the end from
`ReliableDeliverySupervisor`. Any input on that will be much appreciated. I
tested this on a real YARN cluster.

Fix deadlock
We should not askWithReplay in a synchronized block. In this
particular case, the CoarseGrainedSchedulerBackend actor tried
to acquire the same lock when replying, leading to a deadlock.
