> Currently, the way to list snapshots is do a ls on
> <snapshotttableRootPath>/.snapshot directory. Since creation time is not
> recorded , there is no way to actually figure out the chronological order of
> snapshots. The idea here is to add a command to list snapshots for a
> snapshottable directory along with snapshot Ids which grow monotonically as
> snapshots are created in the system. With snapID, it will be helpful to
> figure out the chronology of snapshots in the system.
