Review request for mesos, Gilbert Song, Jason Lai, Jie Yu, and Jiang Yan Xu.

Bugs: MESOS-9319

Repository: mesos


After moving the container root filesystem mounts to the
`filesystem/linux` isolator, these mounts are not logged into the task
sandbox by the container launcher. Since these logs are not generally
useful to tasks, and we did't previously emit them, use the `MS_SILENT`
flag to indicate that they don't need to be logged. Since the kernel
doesn't use `MS_SILENT` for anything, we can safely use it internally.

Diffs (updated)
