[SPARK-12330] [CORE] Fix mesos coarse mode cleanup
In the current implementation the mesos coarse scheduler does not wait for
the mesos tasks to complete before ending the driver. This causes a race where
the task has to finish cleaning up before the mesos driver terminates it with a
SIGINT (and SIGKILL after 3 seconds if the SIGINT doesn't work).
This PR causes the mesos coarse scheduler to wait for the mesos tasks to
finish (with a timeout defined by `spark.mesos.coarse.shutdown.ms`)
This PR also fixes a regression caused by [SPARK-10987] whereby submitting
a shutdown causes a race between the local shutdown procedure and the
notification of the scheduler driver disconnection. If the scheduler driver
disconnection wins the race, the coarse executor incorrectly exits with status
1 (instead of the proper status 0)
With this patch the mesos coarse scheduler terminates properly, the
executors clean up, and the tasks are reported as `FINISHED` in the Mesos
console (as opposed to `KILLED` in < 1.6 or `FAILED` in 1.6 and later)
