Defaults to: One per hour first day, one per day first week, one per week first month, one older. Will read `ovs/framework/scheduling/retention_policy/<vdisk_guid>` for config if different intervals are passed, and will fall back to default if none provided. Todo: -Make unittest pass -Check if config file is in correct format.
Skip the first 24hours when scheduling the task to allow the user to create and use snapshots
Added documentation Extra checks added to the scheduled task to prevent the policy being enacted on a wrong timestamp
