DescriptionReporting: Implement delivery agent.
Reporting is a spec for delivering out-of-band reports from various
other parts of the browser. See http://wicg.github.io/reporting/ for
the spec, or https://goo.gl/pygX5I for details of the planned
implementation in Chromium.
The delivery agent takes the queued reports in the cache, figures out
(with the help of the EndpointManager) where to deliver them, and sends
the serialized reports using the Uploader.

What is disallowed is multiple *uploads*, not multiple *reports*. An upload can contain an infinite number of reports. (Actually, that might be something we want to cap at some point.) I've added a note below the concurrency explanation to clarify that an upload can contain multiple reports, in case anyone else has this question. https://codereview.chromium.org/2739483002/diff/80001/net/reporting/reporting...

It'll be doing exactly that eventually, but I wanted to land the basic delivery code first. https://codereview.chromium.org/2739483002/diff/140001/net/reporting/reportin... net/reporting/reporting_delivery_agent.h:90: // (Would be an unordered_set, but there's no hash on pair.)

Adding a hash is Not My Problem, but using the best data structure available in my code is.
