perf c2c: Display "Total Stores" as a standalone metrics
The total stores is displayed under the metrics "Store Reference", to
output the same format with total records and all loads, extract the
total stores number as a standalone metrics "Total Stores".
After this patch, the tool shows the summary numbers ("Total records",
"Total loads", "Total Stores") in the unified form.
