fortio v0.3.0

New big features:

• you can run fortio with infinite duration - until ^C is sent and it will report the results then,
• likewise you can interrupt fortio before the requested duration and it will report the results
• new JSON output for the all the results, including the Histograms - through a new HistogramData type
• try fortio load -json - http://www.google.com/ to output JSON to stdout while the rest of the output is now on stderr

Note the new HistogramData pure data object returned by the APIs - this is an incompatible change but yield very good benefits (ability to programmatically access all the data, json export etc) thus the 0.3.x bump

It also matches the Istio 0.3 dev cycle
