-- Removes an existing snapshot. Snapshots are used in
-- <https://cloud.google.com/pubsub/docs/replay-overview Seek> operations,
-- which allow you to manage message acknowledgments in bulk. That is, you
-- can set the acknowledgment state of messages in an existing subscription
-- to the state captured by a snapshot.
-- When the snapshot is deleted, all messages retained in the snapshot are
-- immediately dropped. After a snapshot is deleted, a new one may be
-- created with the same name, but the new one has no association with the
-- old snapshot or its subscription, unless the same subscription is
-- specified.
