Review request for mesos, Greg Mann and Jiang Yan Xu.


addressed comments, and rebased.

Bugs: MESOS-4893

Repository: mesos


If user is specified in Resource::DiskInfo::Persistence, set the
ownership of the volume to that user. Tasks should have to comply to
ownership of the volume before they can use the volume.
If user is not specified in Resource::DiskInfo::Persistence, it is
created with the user mesos-slave process runs as. When the first
task is launched, it updates the ownership of the persistent volume
with its user so as to be able to write into that volume.
Note that tasks can fail to use the volume when they actually try
to access the volume is that task's ownership is not compatible
with that of the volume.
