------------------------------------
Summary: Mounts created by executor when using filesystem
isolation are leaking to the host filesystem's mtab

In theory this should not be happening, because the executor should be running
in its own mount namespace. In practice... something is awry. Should talk to
Mesos folks to see what's going on, but we have a few easy solutions regardless:
add the -n flag to the mount command to not create the mtab entry.
run the mount commands through mesos-containerizer launch's --pre-exec which
will create the mount in the isolated fileystem's namespace.
