Review request for mesos, Benjamin Hindman, Gilbert Song, and Kevin Klues.


Bugs: MESOS-6145
    https://issues.apache.org/jira/browse/MESOS-6145


Repository: mesos


Description
-------

The bind mounts in the pid namespace isolator turns out to be
unnecessary as the linux launcher will use freezer to kill all tasks
anyway. It makes the isolator unnecessarily complex, and has a mount
leak bug (MESOS-6145). This patch removes all the unnecessary bind
mounts, making the isolator extremely simple.
