And my other CL from Tuesday, which also ran into flaky failures...  This is how
I see merging merging URLrequestContext creation logic for the OTR and non-OTR
paths.  Once I have all creation in a single place, I'll switch over to using
the builder, then move out the builder delegate class, and the code to call
it...Making a BuilderBuilder (Which I want to eventually get rid of and move the
logic into the network service itself).

The multiple-method delegate approach seems a bit easier to incrementally remove
stuff from than pushing everything to the construction method, also more closely
fits with the existing code here.
