> 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).
