URLRequestContextBuilder:  Add the ability to create a ReportingService.

This is part of the effort to move ProfileIOData over to using
a URLRequestContextBuilder (From there, we'll merge URLRequestContext
creation logic in ProfileIOData and IOThread, move that into a component,
have the NetworkService onto that component, and then have IOThread and
ProfileIOData use an in-process Network Service to create their
URLRequestContexts, and be able to expose the same API as the
NetworkService for both configuration and issuing requests as well).

I'm not adding unit tests for this, just because testing every feature of
URLRequestContextBuilder in addition to testing things with a
TestURLRequestContext seems a bit silly (Though it would be nifty if we use the
URLRequestContextBuilder in more unit tests.  Maybe some day...)
