Issue MESOS-3205: No need to checkpoint container root filesystem path.
Given the design discussed in [MESOS-3004|https://issues.apache.org/jira/browse/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., //xxx).
