        Most arguments are identical to the form fields listed in
        https://developers.google.com/storage/docs/reference-methods#postobject, but
        there are a few differences:

        * The expires argument takes a number of seconds since the epoch.
        * The key argument only specifies the key name, not the bucket.
        * The metadata argument is a dictionary of metadata header names to values.
          Each one is transformed into an x-goog-meta- field. The keys should not
          include "x-goog-meta-". Null values are ignored.
        * The policy document is automatically created and signed. It ensures that
          all fields have the assigned values when they're submitted to Cloud
          Storage.

        The lifetime argument specifies how long the form is valid. It defaults to
        ten minutes.

        The size_range argument should be a tuple indicating the lower and upper
        bounds on the size of the uploaded file, in bytes.
