[SPARK-11809] Switch the default Mesos mode to coarse-grained mode
Based on my conversions with people, I believe the consensus is that the coarse-grained mode is more stable and easier to reason about. It is best to use that as the default rather than the more flaky fine-grained mode.

Closes #9795 from rxin/SPARK-11809.

However, it comes with a risk of less predictable latency, because it may take a while for an application to gain back cores on one node when it has work to do. To use this mode, simply use a -`mesos://` URL without setting `spark.mesos.coarse` to true. +`mesos://` URL and set `spark.mesos.coarse` to false. Note that none of the modes currently provide memory sharing across applications.
