'Store an object in GS using the name of the Key object as the
key in GS and the contents of the file named by \'filename\'.
See set_contents_from_file method for details about the
parameters.
:type filename: string
:param filename: The name of the file that you want to put onto GS.
:type headers: dict
:param headers: (optional) Additional headers to pass along with the
request to GS.
:type replace: bool
:param replace: (optional) If True, replaces the contents of the file
if it already exists.
:type cb: function
:param cb: (optional) Callback function that will be called to report
progress on the upload. The callback should accept two integer
parameters, the first representing the number of bytes that have
been successfully transmitted to GS and the second representing the
total number of bytes that need to be transmitted.
:type num_cb: int
:param num_cb: (optional) If a callback is specified with the cb
parameter this parameter determines the granularity of the callback
by defining the maximum number of times the callback will be called
during the file transfer.
:type policy: :py:attribute:`boto.gs.acl.CannedACLStrings`
:param policy: (optional) A canned ACL policy that will be applied to
the new key in GS.
:type md5: tuple
:param md5: (optional) A tuple containing the hexdigest version of the
MD5 checksum of the file as the first element and the
Base64-encoded version of the plain checksum as the second element.
This is the same format returned by the compute_md5 method.
If you need to compute the MD5 for any reason prior to upload, it\'s
silly to have to do it twice so this param, if present, will be
used as the MD5 values of the file. Otherwise, the checksum will be
computed.
:type res_upload_handler: :py:class:`boto.gs.resumable_upload_handler.ResumableUploadHandler`
:param res_upload_handler: (optional) If provided, this handler will
perform the upload.
:type if_generation: int
:param if_generation: (optional) If set to a generation number, the
object will only be written to if its current generation number is
this value. If set to the value 0, the object will only be written
if it doesn\'t already exist.'
