Pagination support for `cinder snapshot-list`

Issue

• If there are large number of cinder snapshots (for ex. 37k) then, returning this much data is not feasible from a performance perspective, so the osapi_max_limit configuration parameter, which defines the maximum number of entries that can be returned from an API call has been returned to the default of 1000.

• In the case of Cinder volumes, returning the full set of volumes requires multiple API calls, which use pagination to retrieve the data. However pagination support for cinder snapshots does not appear to be present in the API.
