Review request for mesos and Jiang Yan Xu.



Bugs: MESOS-4324

Repository: mesos


Allow the task to specify the persistent volume access to be read-only
or read-write. Note that the persistent volume is always created as
If the task is the first consumer of the shared persistent volume, then
set the ownership of the persistent volume to match that of the task.
Otherwise, allow the task to be executed only if the ownership of the
persistent volume matches that of the task.
Added an option to run the test in mixed (default) mode or shared-only
mode. In mixed mode, multiple shards alternate between shared and
unshared persistent volumes for the tasks. In shared-only mode, all
shards use shared persistent volumes for the tasks.
