A lot of plumbing to get this value from here to where its needed and adds as
coded adds an odd bit of state to this otherwise stateless class. A different
approach might eliminate some of the plumbing (maybe) and put it next to other
similar plumbing (definitely).

ServiceWorkerRequestHandler::InitializeHandler(
   p1, sw_context_wrapper,...,
   filter_->blob_storage_context());

That method is how we associate the swcontext with a requesthandler which is
very similar in nature.
