Bug description:
  env: master branch, Glance using swift backend.

  We hit a strange error， if we upload a large image (larger than 1G),
  the glance_store will hit a error:Unicode-objects must be encoded
  before hashing. But if the image is small enough, the error won't
  happen.

  error log:

  After dig into the code, it appears that when chunk reading the image
  data, the date piece may be non-byte, so the checksum.updating will
  raise the error.

  encoding the date piece to ensure it's byte can solve the problem.
