[SPARK-15994] [MESOS] Allow enabling Mesos fetch cache in coarse executor
backend
Mesos 0.23.0 introduces a Fetch Cache feature
http://mesos.apache.org/documentation/latest/fetcher/ which allows caching of
resources specified in command URIs.
This patch:
* Updates the Mesos shaded protobuf dependency to 0.23.0
* Allows setting `spark.mesos.fetchCache.enable` to enable the fetch cache
for all specified URIs. (URIs must be specified for the setting to have any
affect)
* Updates documentation for Mesos configuration with the new setting.
This patch does NOT:
* Allow for per-URI caching configuration. The cache setting is global to
ALL URIs for the command.
