> With ordered snapshot feature turned on, a snapshot will be just marked as
> deleted but won't actually be deleted if its not the oldest one. Since, the
> snapshot is just marked deleted, creation of new snapshot having the same
> name as the one which was marked deleted will fail. In order to mitigate such
> problems, the idea here is to rename the snapshot getting marked as deleted
> by appending deletion timestamp along with snapshot id to it.
