This CL moves mPerUidCounter.incrementCountOrThrow from
NetworkRequestInfo constructor to the caller of NetworkRequestInfo
constructor and stop incrementing counter for internal NetworkRequestInfo
(e.g. per-app default requests).
Also, this CL update CS not to modify perUidCounter when CS updates
apps' track default network request when the per-app default request is
updated since this does not change the number of request for each uids.
