> Currently, if a container uses container image, we'll do a bind mount of its sandbox (<sandbox> -> <rootfs>/mnt/mesos/sandbox) in the host mount namespace.
> However, doing the mounts in the host mount table is not ideal. That complicates both the cleanup path and the recovery path.
> Instead, we can do the sandbox bind mount in the container's mount namespace so that cleanup and recovery will be greatly simplified. We can setup mount propagation properly so that persistent volumes mounted at <sandbox>/xxx can be propagated into the container.
