Review request for mesos, Xudong Ni, Gilbert Song, Jie Yu, Jacob Janco, and Jiang Yan Xu.

Summary (updated)

Added filesystem operations to the `ContainerLaunchInfo` message.

Bugs: MESOS-9769

Repository: mesos

Description (updated)

The `filesystem/linux` isolator was using pre-exec commands
to set up Linux ABI symlinks, which is inefficient since it
ends spawning `ln(1)` a number of times. The fix adds a new
`ContainerFileOperation` message to the containerizer launch
information. The containerizer executes the requested file
operation after performing the container mounts.
