-- Updates the settings that specify delivery of log files. Changes to a trail
-- do not require stopping the CloudTrail service. Use this action to designate
-- an existing bucket for log delivery. If the existing bucket has previously
-- been a target for CloudTrail log files, an IAM policy exists for the bucket.
