          Gets all snapshots of a volume. Returns a list of snapshots based on optional sorting and filtering, and
          constrained by start and count parameters.
  
          Args:
              volume_id_or_uri:
                  Can be either the volume id or the volume uri.
              start:
                  The first item to return, using 0-based indexing.
                  If not specified, the default is 0 - start with the first available item.
              count:
                  The number of resources to return. A count of -1 requests all items.
                  The actual number of items in the response might differ from the requested
                  count if the sum of start and count exceeds the total number of items.
              filter (list or str):
                  A general filter/query string to narrow the list of items returned. The
                  default is no filter; all resources are returned.
              sort:
                  The sort order of the returned data set. By default, the sort order is based
                  on create time with the oldest entry first.

              list: A list of snapshots.
