Description

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.
