> 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.

> * 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.
