Description

Given the design discussed in MESOS-3004, one container might have multiple provisioned root filesystems. Only checkpointing the root filesystem for ContainerInfo::image does not make sense.

Also, we realized that checkpointing container root filesystem path is not necessary because each provisioner should be able to destroy root filesystems for a given container based on a canonical directory layout (e.g., <appc_rootfs_dir>/<container_id>/xxx).
