google-cloud-rpc breaking changes

• v0.8.0 \u2192 v0.9.0breaking

  We removed all_bytes() helper. This used to copy all the bytes into a single buffer. This is dangerous (the download may consume up to 5TiB of RAM, or maybe double this in some cases), and misleading (the data copy was not obvious). We are planning to restore the function with maybe a different signature.
