Issue MESOS-2971: Implement OverlayFS based provisioner backend
Part of the image provisioning process is to call a backend to create a root filesystem based on the image on disk layout. The problem with the copy backend is that it's both waste of IO and space, and bind only can deal with one layer. Overlayfs backend allows us to utilize the filesystem to merge multiple filesystems into one efficiently.
