Upgrade fog-google and google-api-client to support Cloud Run

Summary

We should upgrade fog-google and google-api-client as soon as a version of fog-google is released that relaxes the dependency on google-api-client.

Improvements

We currently use a version of fog-google which has a hard dependency on an old version of google-api-client that is missing features we need to provision GKE clusters with Cloud Run enabled. We're working around this using a monkeypatch in config/initializers/google_api_client.rb, but we should remove this monkeypatch as soon as a new version of fog-google is released to RubyGems that relaxes the dependency that will allow us to upgrade google-api-client to a version >= 0.26.0.
