The `report-to` directive wires CSP violation reports up to the Reporting API which allows the browser to bundle multiple reports when sending them to the server rather than creating a POST for each individual report. This allows reports to be collected in a way that is friendlier for users' batteries. This change also deprecates the existing `report-uri` directive.
