Reason for revert:
This causes download_from_google_storage to fail:
Failure: CA certificates file does not have expected SHA1 sum; expected: ed024a78d9327f8669b3b117d9eac9e3c9460e9b, actual: 433e5589520cd2f1f29dea3e077cfbc2b74fb78c.
You'll need to also update the expectations on the gsutil side, and then reland.
Test it by running "gsutil ls".
