cubicweb #2465388 make jsonp anonymisation configurable [done]

jsonp controller anonymizes connection before executing any query for CSRF / safety reason. In some cases however (e.g. intranets), it would be nice to authorize authenticated queries. CubicWeb should provide a anonymize-jsonp-queries option, set to True by default.
