Add wheels for google-cloud-logging dependencies.

TEST=`create_venv3 chromite/venv/requirements.txt`

These changes down-version google_api_core to 1.19.0
and protobuf to 3.11.3, to match current ebuild constraints.
I downloaded google_auth 1.14 to avoid downloading the very latest
because google_api_core 1.19.0 only needs google_auth 1.14.0.
Note that we already have protobuf 3.11.3 in the tree, so no packages
were needed for this.

I verified this with running
 pip download --only-binary=:all: -r ../chromite/venv/requirements.txt -d pip_packages/ --find-links pip_packages/
and it only installed one additional package (grpcio-1.33) but
said that was to satisfy grpcio>=1.0rc1, but we are currently on

pip download commands used:
 pip download --python-version 36 --abi cp36m "google_api_core==1.19.0" --only-binary=:all: --dest=pip_packages
 pip download --python-version 36 --abi cp36m "protobuf==3.11.3" --only-binary=:all: --dest=pip_packages
 pip download --python-version 36 --abi cp36m "google_auth==1.14.0" --only-binary=:all: --dest=pip_packages

Additional files pulled in from new pinned versions in requirements.txt,
which will be a follow-on CL.
