(self, file_id, filename, source,
                                   chunk_size_bytes=None, metadata=None)
Uploads a user file to a GridFS bucket with a custom file id.

        Reads the contents of the user file from `source` and uploads
        it to the file `filename`. Source can be a string or file-like object.
        For example::

          my_db = MongoClient().test
          fs = GridFSBucket(my_db)
          file_id = fs.upload_from_stream(
              ObjectId(),
              "test_file",
              "data I want to store!",
              chunk_size_bytes=4,
              metadata={"contentType": "text/plain"})

        Raises :exc:`~gridfs.errors.NoFile` if no such version of
        that file exists.
        Raises :exc:`~ValueError` if `filename` is not a string.

        :Parameters:
          - `file_id`: The id to use for this file. The id must not have
            already been used for another file.
          - `filename`: The name of the file to upload.
          - `source`: The source stream of the content to be uploaded. Must be
            a file-like object that implements :meth:`read` or a string.
          - `chunk_size_bytes` (options): The number of bytes per chunk of this
            file. Defaults to the chunk_size_bytes of :class:`GridFSBucket`.
          - `metadata` (optional): User data for the 'metadata' field of the
            files collection document. If not provided the metadata field will
            be omitted from the files collection document.
