Measure time taken for negotiation in protocol V2

Reason why this change is needed:
Getting this metric will help estimate how much time is spent
on negotiation in fetch V2.

What this patch does:
Measure time spent on negotiation rounds in UploadPack.fetchV2()
and save it in an instance of PackStatistics.Accumulator.
This is the same way the statistics are already gathered for
protocol V0/V1.
