Description

Currently some of Ozone's list APIs are implement in a way that last element from the last page's response is sent as continuation token rather than server providing it. Because of that it makes an extra call to know the ending of response. Hence metrics are also not correct for those paginated APIs HDDS-9983.
We should change this to explicit return the continuation token for the paginated API and use that to fetch next page rather than using last element from the last page's response
