Description

Metrics should be added for snapshot.

From Matteo: Output that we have in SnapshotInfo should be covered:

"%d HFiles (%d in archive), total size %s (%.2f%% %s shared with the source table)"

Jesse mentioned snaphot counts, average time to completion.
I think we should have counts for successful / failed snapshots.
