-- Deletes the specified snapshot.
--
-- When you make periodic snapshots of a volume, the snapshots are
-- incremental, and only the blocks on the device that have changed since
-- your last snapshot are saved in the new snapshot. When you delete a
-- snapshot, only the data not needed for any other snapshot is removed. So
-- regardless of which prior snapshots have been deleted, all active
-- snapshots will have access to all the information needed to restore the
-- volume.
--
-- You cannot delete a snapshot of the root device of an EBS volume used by
-- a registered AMI. You must first de-register the AMI before you can
-- delete the snapshot.
--
-- For more information, see
-- <https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-deleting-snapshot.html Delete an Amazon EBS snapshot>
-- in the /Amazon Elastic Compute Cloud User Guide/.
