better report on errors

[gserra-olx]

1.5M requests of 2M failed

I can't tell if they were timeouts or what else, there is no trace in the logs

Try storing the output in a json format with a parameter 'o'. You will have all the errors which will show the timeouts and other specs.
goad -i -c 100 -u url -n 100 -o test1.log ;
