-- Deletes the specified manual snapshot. The snapshot must be in the
-- 'available' state, with no other users authorized to access the
-- snapshot.
--
-- Unlike automated snapshots, manual snapshots are retained even after you
-- delete your cluster. Amazon Redshift does not delete your manual
-- snapshots. You must delete manual snapshot explicitly to avoid getting
-- charged. If other accounts are authorized to access the snapshot, you
-- must revoke all of the authorizations before you can delete the
-- snapshot.
