[VCN02] Make LingerTimer takes request Id instead of NetworkRequest
Currently, LingerTimer takes a NetworkRequest for internal use.
However, this is unnecessary since only request Id is used.
Thus, this patch allows subsequent patches to remove the need
of a NetworkRequest when creating a LingerTimer. And the output
of lingered requests is reduced to id instead of printing
content of requests.
