[ Merge of http://go/wvgerrit/120510 ]

* Added some comments to clarify which clock times are computed at the
  client and at the provisioning service. More detail is present in the
  device_files.proto
* Moved helper methods |SetDeviceCertificate| and
  |ExtractFromDeviceCertificate| from class methods to anonymous
  namespace
* Removed some commented out code
