Turned on the mesos agent flag '--volume_gid_range'.

When this flag is specified, if a task running as non-root user uses
a shared persistent volume or a PARENT type SANDBOX_PATH volume, the
volume will be owned by a gid allocated from this range and have the
`setgid` bit set, and the task process will be launched with the gid
as its supplementary group to make sure it can access the volume.
