This helps loading http_pb2 and annotations_pb2.
Without this, the Python importer will not be able to process the lines:
from google.api import http_pb2 or
from google.api import annotations_pb2
(Without importing these, the protobuf loader will not recognize http options
in the protobuf definitions.)
