Add UMA metrics for detecting and reporting update certificate changes.
LibcurlHttpFetcher checks if the update server certificate has changed
since last update, and stores an eventual report in prefs. UpdateCheckScheduler
submits to UMA reports from the previous update.
BUG=chromium-os:19842
TEST=Included unittest for the new class and tested locally on an Alex device,
since we need to verify against the actual server certificates.
