PTAL

I will run this with generate_perf.py -E on master1 as soon as it lands so that
test data is temporarily stored in the old framework again (at the moment, test
names are broken). 

I am not entirely sure if it will work though, since we have hierarchical names
on the new dashboard. But I assume the name for the old dashboard is build from
the step log line annotation, e.g.: graphs.dat@endure_gmail_exp_col_live
