Description

When previous key is set as part of list calls [listVolume, listBuckets & listKeys], the result includes previous key, there is no need to have this in the result.
Since previous key is present as part of result, we will never receive an empty list in the subsequent list calls, this makes it difficult to have a exit criteria where we want to get all the values using multiple list calls (with previous-key set).
