debug/io-stats: add an option to set volume-id
'volume-id' is good to have for a graph for uniquely identifying it. Add it to graph->volume_id while generating volfile itself. This can be further used in many other places. Updates: #763 Change-Id: I80516d62d28a284e8ff4707841570ced97a37e73 Signed-off-by: Amar Tumballi <amar@kadalu.io>
